Resumen

Based on the ANSYS, castellated lightweight steel portal frames are modeled to analysis the stress destruction process and stress distribution rule under horizontal and vertical loads. The comparative analysis with the original solid-webbed portal frame in yield load, ultimate load, the mid-span deflection is pursued. The results show that: there are some differences in failure mode between the castellated lightweight steel portal frame after expansion and the original solid-webbed portal frame. The former bearing capacity and rigidity increase by a large scale than the latter.

Resumen

The paper investigates the strength and behavior of the portal steel frame under the consideration of working 3D models. In terms of design, the industrial buildings have been separated into a single portal frame to simplify the design process. This point of view is suitable for structures in that the applied loads are equally distributed to all frames. The fact that the crane loads including vertical and horizontal loads only directly affected one or several portal frames. Therefore, a 3D model of a whole single-story steel industrial building is simulated in a finite element software program

Resumen

As the construction industry, especially steel construction, contributes to a large portion of global greenhouse gas emissions, sustainable structural design has become a necessity to achieve the world vision of reaching net zero emissions by 2050. As steel portal frames are the most used structural system for single-story buildings, the main objective of this study is to determine the optimal steel portal frame configuration using prismatic and/or non-prismatic members to achieve the least embodied carbon. Five different portal frame configurations are considered under the effect of five dist

Resumen

This paper introduces a novel steel portal frame system, in which cold-formed nested tapered box members are used in the design. The bird and dust proofing features of the system make it useful for applications where clean work areas are required, such as food, storage, and manufacturing industries. The new section used in the portal frames comprises two cold-formed channels welded to each other, forming a box-shaped steel member, either tapered or prismatic along its length. Such sections possess high torsional stiffness compared with the conventional I-sections; therefore, lateral bracing em

Resumen

Portal frames with built-up cold-formed cross-sections hold significant potential; however, there is a notable gap in the analysis of cross-section types and connections. In this study, an optimization algorithm was developed for the closed cross-sections of portal frame members. An optimization algorithm was tested against optimized open cold-formed cross-sections. The results indicated a portal frame volume up to 38% lower where members were assembled of optimal closed cross-sections when compared to frames with optimal open cross-sections.

The nonlinear stiffness matrix method was incorporated to investigate the structural performance of steel portal frames with semirigid connections. A portal frame with unstiffened extended end-plate connection was designed to demonstrate the adequacy of the proposed method. Besides, the seismic performance of steel portal frames with semirigid connections was investigated through time history analysis where kinematic hysteresis model was assigned to semirigid connections to account for energy dissipation and unloading stiffness.

Resumen

Stability has been an important subject in the design of a portal frame structure. Conventional stability analysis of the portal frame is normally conducted assuming that all the joints are rigid. However, the joints of a portal frame in real applications are not always rigid and semirigid connections often exist. AISC design code requires that the effect of the joint flexibility on the behavior and buckling capacity of the portal frame should be taken into account in the analysis and design procedures. To address this issue, a portal frame with flexible joints and rigid members was theoretica

The true strength and deflection behaviour of industrial and commercial steel portal frame buildings is understood better if the effects of stiffness of end frames and profiled steel claddings are included. The conventional designs ignore these effects and are very much based on an idealised twodimensional frame behaviour.

Resumen

The traditional approach for the design of steel portal frame building systems is based on the idealised two-dimensional behaviour of a bare internal frame in the system. This approach totally ignores the integral action of other structural components in the system. In order to design the portal frame building system based on its 'true' threedimensional behaviour, it is necessary that other structural components such as steel roof and wall cladding systems and end frames (or their effects) are included in the analysis. In the UK and USA, this has been achieved using the principles of str

Resumen

Light-frame shearwall assemblies have been successfully used to resist gravity and lateral loads, such as earthquake and wind, for many decades. However, there is a need for maintaining the structural integrity of such buildings even when large openings in walls are introduced. Wood portal frame systems have been identified as a potential alternative to meet some aspects of this construction demand. The overarching goal of the research is to develop wood portal frame bracing systems, which can be used as an alternative or in combination with light-frame wood shearwalls. This is done through in

Resumen

<p>For certain bridge types, the influence of soil-structure interaction (SSI) may have an important contribution to the stiffness and damping of the structural system. From a design point of view, this influence may be both conservative and non-conservative and therefore, an increased knowledge within this field could lead to better design assumptions. In terms of maintenance, assessment and upgrading of existing structures, an increased knowledge of the phenomena and parameters which govern the soil-structure interaction, may lead to more realistic models and thereby, to more precise informa

Resumen

The effect of different vertical support stiffness of a frame railway bridge is investigated in this study. Due to the dynamic loads of the high speed trains that run over the railway bridges, the response of these structures is far from the static effects. The frame bridge chosen for this study is the Rössjö bridge, located on the Bothnia Line, the first high speed railway built in Sweden. Using a theoretical model of this bridge, the eigenfrequencies of the structure and the vertical accelerations of the deck are evaluated. Not only different vertical support stiffness, but also different tr

The load-carrying capacity of two old steel portal frame bridges, built in 1907 and 1912 has been determined, using FE-models and taking into account the damage due to corrosion, found during inspection. For this, adequate real traffic models have been used. The capacity of both bridges proved to be insufficient, mainly due to corrosion of the outside portals. The frame cross-sections are asymmetrical, since reduction of the area is considered for tension and not for compressed parts. Two alternatives are considered for refurbishment.

In this study, thermal simulations and stress calculations on a model of a portal frame bridge are performed with the aim of evaluating the temperature difference between the bridge parts. It is shown that the temperature difference between parts which is proposed by Eurocode 1 is overestimated, thus the resulting stress distribution being unrealistic.

This paper investigated the flexural behavior of the bolted gusset-plate joint applied in the beam-beam connection of aluminum alloy portal frames. Bending tests were conducted on 3 aluminum alloy bolted gusset-plate joints. The failure phenomenon indicated that the thin plate joint failed by the buckling of gusset plates, while the thick plate joint failed by the buckling of sleeves. The momentrotation curves showed that thickening the gusset plate can effectively prevent the buckling of gusse

Resumen

The use of portal frame systems composed of cold-rolled aluminium profiles is likely to be a new structural solution in corrosive environments. In such structural systems, stainless steel bolts are commonly used as connectors to fasten various aluminium components in the full-scale systems. In these connections, the point fasteners may experience either shear force, torque and/or a combination of both, leading to complex behaviours of the connections. While the failure may occur at a bolt, the other structural components are still in the elastic state. Hence, investigation into the load-deform

Resumen

Built-up cold-formed steel (CFS) unsymmetrical angles are increasingly used in structures such as portal frames, roof trusses, and transmission towers. However, there are limited studies on CFS unequal back-to-back angle columns (BBUAC) with stiffeners. This paper presents the results of six experimental tests on intermediate BBUAC with intermittent screw fasteners. The findings include the deformed shapes at failure and the load-axial shortening behavior. Additionally, a nonlinear finite element (FE) model that accounts for both material and geometric nonlinearity was developed. The experimen
