Abstract:

This research aims to compare Timber concrete slabs (TCC) with solid slabs (RC) to show that TCC may be used to minimize building weight and construction costs. Moreover, the purpose of this project is to use CypeCAD software to design a one-way TCC slab and a two-way solid slab, analyze the data supplied in the software, and compare the findings according to the Eurocode standard. The results illustrate that although the timber concrete composite slab is a new constructive solution and is little used in many constructions, it is less expensive compared to the conventional solution adopted in

Abstract:

Abstract Construction with flat slabs is quite dangerous when there is strong earthquake shaking. Two different forms of flat slab buildings—flat slab with shear wall at core and flat slab with x-bracing—are considered in the study. These flat slab constructions’ structural rigidity is increased by this lateral force-resisting mechanism. It has been found that adding a shear wall considerably boosts the flat slab structure’s ability to withstand lateral forces.

Abstract:

Cost is an important factor in choosing the type of floor or slab used in any construction. When a large space within a building needs to be covered without hindrance and supports, waffle or ribbed slabs are used. For all slab systems, the cost constitutes a significant portion of the overall cost of the structure. Therefore, this research aims to select a preferable slab system with the least construction cost for a shopping mall. Computer-aided design software such as Prota 2018 and Orion 2018 was used for analysis and design, and RCC spreadsheets were used to manually check the slabs. The r

To reduce resource consumption and the carbon footprint of the construction industry, new construction principles that stipulate the minimisation of materials are urgently needed.

A promising approach is the use of corrosion-resistant carbon fibre-reinforced polymer (CFRP) reinforcement, which requires only a small concrete cover to meet bond requirements.

Over the past decades, there has been a tremendous improvement in the concrete placement technology in Uganda. The methods have moved from being manual to the use of concrete pumps. A concrete pump is capable of pumping high volumes of concrete per minute. This implies that for small volume slabs before the setting of concrete, the whole weight of the fresh concrete of the upper slab, formwork, and props is transferred to the lower supporting slab. During construction, slabs are stacked with materials like bricks, blocks, sand, and aggregates. Construction loads such as block loads and loads d

Abstract:

Bubbled slabs are used to reduce the overall weight of the slab by minimizing the volume of concrete in the central portion of the slab. This drop leads to cost savings, a decrease in building time, enhancements in structural performance, and an improvement in the efficiency of the slab. Although this slab style has several advantages, it is comparable to flat slabs. The higher stress concentration at the column connection leads to failure due to punching shear. Furthermore, as recommended by construction regulations, the design equations for bubbling slabs are based on experimental data obtai

Abstract:

Abstract The regular slab is often supported by a beam in modern construction, With a modest slab width and a big beam deep, the weight is transmitted from beam to column. Because of the flat slab, architects may construct partition walls wherever they are required. It is popular since it assists with weight reduction, stimulates quick development, and is did-not expensive. Similarly, since its debut, the classic slab has brought benefits such as greater rigidity. It offers a higher weight bearing capacity while also being good and economical. Grid slabs are required if the span is higher than

In this paper, the rib beam bridge slabs were taken as the research object. Static load and fatigue tests were carried out on the benchmark bridge slabs to determine the ultimate load capacity and fatigue life of the bridge slabs. Then, the bridge slab was pre-damaged and reinforced with polyurethane concrete. A fatigue test was carried out on the reinforced bridge slab to study the fatigue performance. Based on the damage theory, the fatigue damage reinforcement finite element models of the bridge slabs under different damage degrees were established. The fatigue performance of the reinforced

This study presents experimental and numerical investigations on seven one-way, reinforced concrete (RC) slabs with a new technique of slab weight reduction using polystyrene-embedded arched blocks (PEABs). All slabs had the same dimensions, steel reinforcement, and concrete compressive strength. One of these slabs was a solid slab, which was taken as a control slab, while the other six slabs were cast with PEABs. The main variables were the ratio of the length of the PEABs to the length of the slab (lp/L) and the ratio of the height of the PEABs to the total slab depth (hP/H). The minimum dec

Slabs are vital for supporting loads and forming the foundation for structures' floors and roofs, classified as one-way or two-way based on deflection characteristics. A recent innovation in construction, the Reinforced Bubble Deck Concrete (RBDC) slab, integrates spherical or elliptical hollow bubbles within the slab for reinforcement, reducing concrete usage without compromising structural integrity. This unconventional approach diverges from traditional methods. The manuscript thoroughly reviews existing literature on the design and testing of Reinforced Bubble Deck Concrete slabs, aiming t

The service environment of civil air defense engineering structures is relatively harsh, and the corrosion of steel bars is the main reason for reducing the durability of concrete structures in civil air defense engineering. A hybrid FRP–steel-reinforced concrete (hybrid-RC) structure has excellent durability. Therefore, it is a good choice to apply hybrid-RC to civil air defense engineering structures. In order to study the blast resistance of hybrid-RC structures, close blast and contact blast experiments were carried out on hybrid-RC slabs, steel-reinforced concrete (SRC) slabs and GFRP-rei

Usually, these structures are employed to counteract the sizeable moments brought on by applied stresses.

Test results show that the deformation of the prefabricated steel truss concrete slab in construction stage meets the requirement of the Code, and the slab is mainly controlled by deflection instead of cracks;

The purpose of this study is to investigate the failure behavior of wall–slab joints and the effect on the collapse of the two types o

A comparative study has been done between post-tensioned, and reinforced concrete flat slab to compare how much each slab cost.

Laminated concrete slabs can deliver desirable structural properties and effectively improve the speed of construction. According to their basic specifications, laminated concrete slabs comprise a 60 mm precast concrete slab and a 70 mm concrete layer cast in situ, with a steel truss bar at a height of 80 mm. This paper studies the effects of the steel truss bar on the mechanical properties of precast slabs. A simple but accurate method is proposed for calculating the stiffness of precast slabs. The test results show that the steel truss bar has a limited effect on the stiffness of the precast
