This research investigated the behaviour of sandwich profiled steel sheet composite wall (PSSCW) and oriented strand board composite wall (OSBCW) with infill commercial form material (CFM). The axial load behaviour of PSSCWs and OSBCWs having different height to width ratio and PSS/OSB-CFM connector spacing was analysed based on experimental results of strength, load-deformation response, load-strain development and failure modes. In addition, flexural behaviour of OSBCW and the thermal conductivity tests on PSSCW and OSWCW specimens were carried-out. The axial load capacity of PSSCW/OSSCW was increased by 946% to 1714% compared to walls without in-fill and decreased with the increase of height to width and connector spacing to height ratio. The existing analytical equations were found to over predict the axial load capacity of both PSSCWs and OSBCWs. The recommendation of this research will understand the axial, flexural and thermal behaviour of PSSCW/OSBCW with CFM infill for practical building applications.

Axial Load Capacity

Reinforced concrete (RC) columns often require consolidation or rehabilitation to enhance their capacity to endure the loads applied. This paper aims at studying the conduct and capacity of RC square columns, those reinforced with steel jacketing under static preloads. For this purpose, a three-dimensional model of finite element (FE) is devised mainly to investigate and analyze the effect of this case. The model was tested and adjusted to ensure its accuracy using the previous experimental results obtained by the author. Results of testing, experimentally, the new developed FE model revealed the ability to use the model for calculating RC columns’ axial load capacity and for predicting accurate failure modes. The new model that tends to predict the axial load capacity was suggested considering the parametric analysis results.

Wall System

This paper presents the performance of an emerging prefabricated composite system made from profiled steel sheeting and dry board. Six full-scale wall specimens were prepared and tested under axial load. The results of the experimental investigation showed that the performance of the composite walls is governed by the strength of profiled steel sheeting while the dry board performed as a wall sheathed. A partial interaction between the profiled steel sheeting and dry board was achieved by using self-drilling screws. The maximum axial load capacity is 1329kN for the double sheathed wall. The failure behavior of single and double sheathed composite wall exhibited similar pattern such as global buckling and cracking. The developed composite wall system was found the great potential in prefabricated and modular construction in Malaysia.

Code Provisions

The mechanical and physical properties of glass fiber-reinforced polymer (GFRP) reinforcement are different from steel, which requires independent code provisions for GFRP-reinforced concrete (RC) members. The currently available code provisions for GFRP-RC members still need more research evidence to be inclusive. For example, the available provisions for confinement reinforcement of FRP-RC columns do not consider the effects of column aspect ratio, which is not yet supported by any available research data. In this study, two full-scale spirally reinforced GFRP-RC circular columns were constructed and tested under concurrent seismic and axial loads. Both specimens had an aspect ratio (shear span-to-diameter ratio) of 7.0, while other two specimens with an aspect ratio of 5.0, from a previous stage of this study, were included for comparison purposes. For each aspect ratio, each specimen was loaded under one of two levels of axial load; 20 or 30% of the axial load capacity of the column section. All test specimens had a 35 MPa concrete compressive strength, 350-mm diameter, 85-mm spiral pitch and 1.2% longitudinal reinforcement ratio. The experimental results were analyzed in terms of hysteretic response, drift capacity and inelastic deformability hinge length. Based on the experimental results, it can be concluded that the aspect ratio affects the magnitude of secondary moments and inelastic deformability hinge length. In addition, the aspect ratio may affect drift capacity of GFRP-RC columns, depending on axial load level.
