Non-Linear Seismic Analysis of Steel Plate Shear Wall Subjected to Blast Loading

Abstract

Compared to traditional lateral loading systems, such as steel braced frames, RCC walls and moment- frames, Steel plate shear walls (SPSWs) have affordable detailing pre-requisites, requires lower construction tolerances, allows faster construction and leads to less lateral load. Similar to concrete shear walls, SPSW structures are more versatile and due to their versatility, the designer also needs to have additional flexural rigidity when using SPSW in tall buildings. In spite of all advantages, SPSW are not universally accepted because of typical SPSW arrangements result in huge column sizes and forbid the usage of slender walls while reducing the efficiency of the structure. SPSW allow for less structural wall thickness in comparison to the thickness of concrete shear walls. So, it is necessary to design the thickness of a SPSW required for particular load. This paper would address the above issues with concrete examples and suggest approaches for the creation of the next generation of shear walls made of steel plate. Such approaches would allow SPSWs to be applied efficiently by offering new configuration, different modelling techniques and a more detailed understanding of model behaviour by comparing different SPSW thickness and different patterns in a particular structure. The analysis in this study is done by considering a steel structure. Earthquake data is considered for analysis and it is assigned using time history function in SAP 2000. The paper deals with lateral resistance of a steel structure for a seismic loading with different SPSW thickness and patterns. which showed SS2 type steel plate shear wall configuration performing well in resisting bending moment in both directions.
