Abstract:
This paper investigates shear flow strength of insulated concrete sandwich panels with glass fiber reinforced polymer (GFRP) shear connectors based on push-out test. The precast insulated concrete panels consist of 60mm concrete wall, 100mm insulation, and 130mm concrete wall. Two concrete walls were connected with GFRP corrugated shear connector. Four specimens with variables such as the insulation type and the width of GFRP corrugated shear connector were made. Failure modes, shear flow-deflection relationships and post-peak strength were investigated. Test results indicate that the specimens with EPS insulation show higher shear flow strength than those with XPSS insulation due to the relatively high surface roughness of EPS insulation, and the shear flow strength increased with increasing shear connector width.

Abstract:
The application of structural insulated panels (SIP) was mainly limited to wall panels in the past. In order to evaluate the flexural performance of SIP two-way slabs, an experimental research on the flexural behavior of four full-size two-way slabs, made of SIP panels or fiber reinforced structural insulated panels, was presented in this paper. The bending capacities and the strains in the face layers were studied and compared with those of ordinary reinforced concrete two-way slabs. Testing results verified that, strengthening of glass fiber reinforced polymer sheets could obviously improve the flexural capacity of SIP slab. Fiber reinforced structural insulated panels could substitute ordinary reinforced concrete slabs in residential or light commercial buildings.

Abstract:
Structural insulated panel (SIP) is considered as a green panel in construction industry because of the low thermal conductivity of the sandwiched EPS core (i.e extended polystyrene). It is a lightweight composite structure and is widely used in commercial, industrial and residential buildings to construct the building envelop including roof and wall. The windborne debris driven by cyclone or hurricane usually imposes intensive localized impact on the structural panel, which might create opening to the structure. The opening on the building envelope might cause internal pressures increase and result in substantial damage to the building structures, such as roof lifting up and wall collapse. The Australian Wind Loading Code (version 2011) [1] requires structural panels to resist projectile debris impact at a velocity equal to 40% of the wind speed, which could be more than 40 m/s in the tropical area with the wind speed more than 100m/s. In this study, two kinds of SIP under projectile debris impact were investigated, i.e. “Corrolink” and “Double-corrolink” composite panels shown in Fig. 1. Laboratory tests were carried out by using pneumatic cannon testing system to investigate the dynamic response of composite panels subjected to wooden projectile impacts. The failure modes were observed. The structural dynamic responses were also examined quantitatively based on the deformation and strain time histories measured in the tests. The penetration resistance capacity of panels subjected to windborne debris impact was assessed.Fig. 1 Schematic diagrams (L) Corrolink panel; (R) Double-corrolink panel [2]

Abstract:
Moisture dry-out from steel-faced insulated sandwich panels has previously received little attention from researchers. This paper reports the results from laboratory tests and dynamic heat, air, and moisture transport simulations of the moisture dry-out capabilities of a steel-faced sandwich panel with a mineral wool core. Three test walls (TWs) with dimensions of 1.2 m × 0.4 m × 0.23 m were put above water containers to examine the moisture transport through the TWs. A calibrated simulation model was used to investigate the hygrothermal regime of a sandwich panel wall enclosure with different initial moisture contents and panel joint tightening tapes. The moisture dry-out capacity of the studied sandwich panels is limited (up to 2 g/day through a 30-mm-wide and 3-m-long vertical joint without tapes). When the vertical joint was covered with a vapour-permeable tape, the moisture dry-out was reduced to 1 g/day and when the joint was covered with a vapour-retarding tape, the dry-out was negligible. A very small amount of rain would be enough to raise the moisture content to water vapour saturation levels inside the sandwich wall, had the rain ingressed the enclosure. The calculated time of wetness (TOW) on the internal surface of the outer steel sheet stayed indefinitely at about 5500 h/year when vapour-retarding tapes were used and the initial relative humidity (RH) was over 80%. TOW stabilised to about 2000 h/year when a vapour-permeable tape was used regardless of the initial humidity inside the panel. A vapour-permeable tape allowed moisture dry-out but also vapour diffusion from the outside environment. To minimise the risk of moisture damage, avoiding moisture ingress during construction time or due to accidents is necessary. Additionally, a knowledge-based method is recommended to manage moisture safety during the construction process.

Abstract:
Extreme wind events caused damages and losses around the world every year. Windborne debris impact might create opening on building envelop, which would lead to the increase in internal pressure and result in roof being lift up and wall collapse. Some standards including Australia Wind Loading Code (AS/NZS 1170:2:2011, 2011) put forward design criteria to protect structures against windborne debris impacts. Structural insulated panel with Oriented Strand Board skin and expanded polystyrene core has been increasingly used in the building industry. Its capacity was found insufficient to resist the windborne debris impact in cyclonic areas defined in the Australian Wind Loading Code. Therefore, such panels need be strengthened for their applications in construction in cyclonic areas. In this study, impact resistance capacities of seven structural insulated panels strengthened with steel wire mesh and basalt fibre mesh were experimentally and numerically investigated. The impact resistance capacities were identified by comparing the damage mode, residual velocity and unpenetrated length of projectile after impact. Experimental results clearly demonstrated the enhancement of the impact resistance capacities of panels strengthened with steel wire mesh and basalt fibre mesh. Finite element model was developed in LS-DYNA to simulate the dynamic response of the structural insulated panels under windborne debris impact. The accuracy of the numerical model was validated with the testing data.

Abstract:
Thermal efficiency of Precast Concrete Sandwich Panel Walls has become a major topic when discussing the building envelope in academia. At Utah State University, research is being done to evaluate the structural and thermal efficiency of fiber reinforced polymer connectors being used today. In evaluating several different proprietary fiber reinforced polymer systems, researchers plan to develop design procedures to help engineers accurately determine minimum design requirements when using fiber reinforced polymer connectors. This largely requires a determination of the degree of composite action incurred by each system. Testing is performed by constructing small scale specimens (3 ft. by 4 ft., 0.91 m by 1.22 m). Each specimen contains one of the fiber reinforced polymer connecting systems. By constructing a five-wythe, two wall specimen, direct shear can be applied to the connectors using a push-off shear test method. By performing this test it can be determined to what degree the panel is acting compositely. Once the degree of composite action is determined, correlation can be made between design and degree of composite action. Economizing and simplifying this procedure is key to further implementation of precast concrete sandwich panel walls in all areas of our building infrastructure.

Abstract:
The majority of residential construction and a significant portion of light commercial and industrial construction has been, and will continue to be light-framed timber construction. In recent years, innovations have surfaced to improve upon light-framed construction. Structurally insulated panels (SIPS) are gaining popularity due to their superior energy efficiency and ease of construction. Light-framed timber construction has proven to be trustworthy in high-wind and seismic regions due to its lightweight construction and numerous redundancies. Shear walls, along with floor and roof diaphragms, resist lateral loads in a timber structure. In the past, research has focused on the static racking performance of light-framed shear walls. More recently, research has been focused on the cyclic and dynamic performance of shear walls. To the author's knowledge, no other research is reported in the literature on the cyclic performance of SIPS shear walls. It is important to understand and quantify the monotonic and cyclic response of shear walls. In this study, twenty-three full-scale shear walls were tested under monotonic loading and sequential phased displacement cyclic loading. Four different wall configurations were examined. Monotonic and cyclic performance of the shear walls and monotonic and cyclic testing procedures are compared. Response of SIPS shear walls is also compared to the response of light-framed shear walls based on capacity, stiffness, ductility, energy dissipation, damping characteristics, and overall behavior. Results of this study will provide useful information regarding the performance of SIPS shear walls and similar systems subjected to static, cyclic, and dynamic lateral loads.

"measurements. This paper is confined to the different forms of sampling odourous gases for olfactometric measurements and the problems involved. It refers to existing guidelines for olfactometric measurements in the countries of the EEC, as well. 2. TYPES OF SAMPLING Samples of odourous gas may be collected in unconcentrated or concentrated form. Concentrated sampling is usually neces­ sary when gas chromatography or other chemical analytical meth­ ods are to be used. Unconcentrated sampling is provided if o-dour threshold concentrations are required (2). Depending on the type of olfactometer used dynamic sam­ pling or static sampling are provided. The principle of dynam­ ic sampling is shown in Figure 1. It requires a part-flow of the odourous gas to be continoulsy extracted from the source and subsequently directed to the olfactometer. This sampling method implies that the measurements are carried out close to the source. An advantage of the method is that there is the possibility of controlling a process, directly, and in case of the break-down of the process this can be noticed right away. A disadvantage of the dynamic method is that odour sources that are not readily accessible require a relatively great ef­ fort in order to install the olfactometer and suitable sam­ pling pipes which often should be insulated or heated to avoid adsorption or condensation (3). When static sampling is used a partial stream of the o-dourous air is collected in a sampling vessel. Samples are taken from this vessel or bag to dilute the odourous air for the olfactometer using syringes or on-line tubings. When using this method odour measurement with the panel can be carried out at any arbitrary location, if the vessel is a transport­ able one. An example for static sampling is given in Figure 2. 3. PROBLEMS OF SAMPLING the main problems encountered when sampling odourous air derive from surface effects of the sampling tubes and vessels, namely by - adsorption, - desorption, and - condensation. This depends mainly on the material of the tube, the vessel or the bag (adsorption) or on the nature of the gas, whether it is hot and/or containes a high amount of humidity (condensa­ tion). On the other hand the sample can be altered by trace components bleeding from the material of the walls of the ves­ sel or the tube (desorption). The following factors are to be observed for valid static sampli ng. aTTTToTce of_m£teri aj_ For tWe sampling of odourous gases glas vessels, stain­ less steel tanks (4) and flexible plastic bags (5) were tested. The initial concentrations of the test gases decrease consider­ ably with storage time in glass and steel vessels. In recent years bags made of Polyethylene(6), Teflon (3) and Tedlar (7), (8) were usually used. Figure 3 shows a graph from SCHUETZLE."

Abstract:
<p>Structural Concrete Insulated Panels (SCIPs) are relatively new addition to construction industry. SCIPs have previously been used in construction of residential, commercial, and military structures. Despite applications overseas and a few in the United States, SCIPs have still remained a relatively unknown construction methodology among structural engineers in the United States and other countries. SCIPs offer advantages such as fast construction, lightweight, thermal insulation, sound insulation, cost-efficiency, and good seismic and wind performance. These advantages make SCIPs a competitive construction methodology compared to traditional wood and masonry construction. In this study, the SCIP construction is introduced, followed by experimental results from full-scale testing of 14 SCIPs slab and wall panels under gravity and lateral loads. 11 full-scale slabs, ranging from 3-5.5 m (10-18 ft.) span, are tested under four-point bending tests in accordance with ASTM standards. The strength, ductility, and failure pattern of the panels are discussed. In addition, the adequacy of splicing details for SCIP slab panels are investigated experimentally using three 5.5 m (18 ft.) slab panels. Three full-scale cantilever wall panels are tested under quasi-static cyclic loading in accordance with ACI seismic testing load protocols. The wall-to-footing connection is a socket connection. This is a novel type of connection for precast wall connection in seismic regions. Experimental results and observations from testing of slab and wall panels showed good strength, ductility, and performance of the specimens.</p>

Abstract:
A 12′ by 24′ passive solar test building has been constructed on the campus of the University of Louisville. The building envelope is comprised of structural insulated panels (SIPs), 12″ thick, (R-value of 45 ft2F/Btu) for the floor and walls and 16″ (R-63) for the roof. The building is divided into two symmetrical rooms with a 12″ SIPs wall separating the rooms. All joints between panels are caulked to reduce infiltration. Each room contains one window (R-9) on the north side wall, and two windows (also R-9) facing south for ventilation and daylighting, but which will also provide some direct gain heating. The south wall of each room features an opening that will accommodate a passive solar heating system so that performance of two systems can be compared side-by-side. The overhang above the south openings is purposely left short to accommodate an awning to provide adjustable shading. The calculated loss coefficient (UA) for each room of the building is 6.07 W/K. Each room is also equipped with a data acquisition system consisting on an SCXI 1600 16 bit digitizer and an SCXI 1102B isolation amplifier with an SCXI 1303 thermocouple module. Pyranometers are placed on the south wall and the clerestory wall to measure insolation on the solar apertures. For initial tests, one room is equipped with an original heat pipe system previously tested in another building, while the other is equipped with a modified heat pipe system. Changes to the modified system include copper absorbers versus aluminum, an adiabatic section constructed of considerably less thermally-conductive DPM rubber than the copper used for the original design, and one of the five condenser sections of the heat pipes is exposed directly to the room air to provide early-morning heating. Experimental results will be compared to simulations with as-built building characteristics and actual weather data. Previous simulations with a load to collector ratio of 10 W/m2K, a defined room comfort temperature range between 65°F to 75°F, and TMY3 weather data for Louisville, KY, showed that the modified heat pipe wall design improves annual solar fraction by 16% relative to the original design.

Abstract:
<p>Affordable housing plays an important role in providing equal opportunity for individuals within most communities in the United States. In the area of eastern Washington State, in particular, there is currently a dearth of affordable housing options; especially for larger families. This lack of three- and four- bedroom residences presents a challenge for the City of Spokane, and the low-income residents seeking housing. This paper provides a preliminary look at certain alternate construction approaches for stand-alone houses with the end goal of optimizing taxpayer funding available, and to reduce living expenses for occupants. Two possible alternative approaches [structural insulated panels (SIPs) and straw bale wall construction] are compared to traditional wood frame construction; all in terms of cost and structural performance. Alternate foundation options are also currently under consideration. It appears that certain alternate construction techniques are worthy of a fresh look; particularly straw bale construction.</p>

Abstract:
Abstract The DebriSat hypervelocity impact experiment, performed at the Arnold Engineering Development Center, is intended to update the catastrophic break-up models for modern satellites. To this end, the DebrisSat was built with many modern materials including structural panels of carbon-fiber, reinforced-polymer (CFRP). Subsequent to the experiment, fragments of the DebrisSat have been extracted from porous, catcher panels used to gather the debris from the impact event. Thus far, one of the key observations from the collected fragments is that CFRP represents a large fraction of the fragments and that these fragments tend to be thin, flake-like structures or long, needle-like structures; whereas, debris with nearly equal dimensions is less prevalent. As current ballistic limit models are all developed based upon spherical impacting particles, the experiment has pointed to a missing component in the current approach that must be considered. To begin to understand the implications of this observation, simulations have been performed using cylindrical structures at a representative orbital speed into an externally-insulated, double-wall shield that is representative of shielding on the current International Space Station crew transport vehicle, the Soyuz. These simulations have been performed for normal impacts to the surface with three different impact angles-of-attack to capture the effect on the shield performance. This paper documents the simulated shield and the models developed to study the effect of fragments and derives the critical characteristics of CFRP impacting particles for the selected shield. This work gives a deployable form of a critical, non-spherical projectile ballistic limit equation for evaluating non-spherical space debris for orbital debris environment modeling.

Abstract:
A major challenge for solar water heaters is to provide heat at a cost comparable to or lower than conventional fuels. Since the price of a passive integral-collector-storage (ICS) solar water heater has historically been less than that for active systems with freeze protection, they can potentially heat water at a lower cost. However, ICS panels are subject to freeze damage, as the collector generally has metal tubes carrying pressurized water that can freeze and burst. In order to delineate the geographical areas where ICS panels can be deployed safely, it is necessary to experimentally characterize the conditions causing freeze damage, to develop a model relating the freeze behavior to climatic conditions, to validate that model with experimental data, and to run the model against long-term weather data across the U.S. Two variations of an ICS panel and/or their bare tubes were tested in a walk in freezer and subjected to freezing conditions until freeze damage occurred. The units tested include both a single and double glazed tubular ICS panel. Key data includes the volume expansion of the tube(s) at burst and the collector loss coefficient near 0 degrees C. Under freezing conditions the insulated supply/return lines would freeze solid initiating a pressure-buildup and eventual burst in the collector tubes due to further internal freezing. An additional test on the single glazed unit was also conducted in which heat tape was installed on the inlet and outlet pipes to prevent them from freezing, which increases the freeze tolerance of the panel by forcing small internal interconnection pipes to freeze solid before damage occurs. Existing models for ICS thermal performance were modified to incorporate the freezing process, and have been validated with the experimental data. The validated models were used to predict regions of the country that are safe for installing the ICS panels. Simulations were run using 30 years of weather data available for all TMY2 sites, and maps were created to illustrate regions of safe installation throughout the US for both the with and without heat tape scenarios for the two ICS models. A correlation using record minimum temperature was developed to generalize the maps to any location for which the record minimum is known. The maps show quantitatively the expected conclusions: 1) that double glazing and higher insulation will extend the safe region; and 2) that the use of heat tape on the inlet and outlet pipes significantly increases the region in which ICS panels can be safely installed in the US.

Abstract:
Abstract The National Solar Thermal Test Facility (NSTTF) at Sandia National Laboratories is conducting research on a Generation 3 Particle Pilot Plant (G3P3) that uses falling sandlike particles as the heat transfer medium. G3P3 proposes a system with 6 MWh of thermal energy storage in cylindrical bins made of steel that will be insulated internally using multiple layers of refractory materials[1]. The refractory materials can be applied by stacking pre-cast panels in a cylindrical arrangement or by spraying refractory slurry to the walls (shotcrete). A study on the two methods determined that shotcrete would be the preferred method in order to minimize geometric tolerance issues in the pre-cast panels, improve repairability, and to more closely resemble commercial-scale construction methods. Testing and analysis was conducted which showed shotcrete refractories could be applied with minimal damage and acceptable heat loss.

Abstract:
The Columbia River in Washington State is at risk of radioactive contamination — a legacy of the cold war. Two hundred thousand cubic meters (fifty-three million US gallons) of radioactive waste is stored in 177 underground tanks at the Hanford site. This waste, which is 60% of the nation’s radioactive waste, is a product of 50 years of plutonium production for national defense. Bechtel National, Inc. has been commissioned by the U.S. Department of Energy to design and build a vast complex of waste treatment facilities to convert this waste into stable glass using a proven vitrification process. In this vitrification process, radioactive waste is mixed with glass-forming materials, then melted at approximately 1200C, and then poured into stainless steel canisters. These canisters are then permanently stored at secure aboveground or belowground facilities. The vitrification process results in a large amount of heat being stored in the hot glass. This heat must be removed within production schedule constraints. In the vitrification facility this glass is cooled in a small room called the Pour Cave. The room contains insulation to protect the concrete, and ventilation and water-cooled cooling panels to facilitate heat removal. The canister heat release rate depends on the thermal properties of the glass (which varies as the glass recipe changes), and the local environment, which includes other hot glass canisters. The cooling process is extremely complex. It is strongly coupled, and is driven by radiation, forced convection, natural convection and conduction heat transfer. Computational fluid dynamics, CFD, was used to predict the heat load to the ventilation system, the cooling panels and to the insulated concrete walls for a variety of operating conditions, providing the data needed for the design of these systems. Of particular interest was the temperature of the concrete, and whether or not design limits would be exceeded. The paper describes the special techniques that were developed to simulate the Pour Cave. This includes description of the modeling of the pouring of the glass, buoyancy modeling, and initialization of the simulation. Results are presented which show the predicted heat transfer characteristics throughout the Pour Cave.
