Studies on Behaviour of Wall-Frame Structure Subjected to Lateral Load

Shear wall is one of the most commonly used lateral load resisting in high rise building. Shear wall has high in plane stiffness and strength which can be used to simultaneously resist large horizontal load and support gravity load. Shear wall with frame is known as dual structural system or wall- frame structure which is most effective and adequate in resisting of lateral load like earthquake load. The scope of present work is to study the effect of seismic loading on placement of shear wall in medium rise building at different alternative location. The office building of medium raised is analyzed for earthquake force by considering two type of structural system. i.e. Frame system and Dual system. Generally total ten models are considered in which five are of six stories and five are of twelve stories. Effectiveness of shear wall has been studied with the help of three different models of six stories and twelve stories. Model one and six are bare frame structural system, model two and seven are full masonry infill and other three models of six story and twelve story are dual type structural system. Analysis is carried out by using standard package ETAB (Extended Three dimensional Analysis of Building System). In which Seismic analysis using both linear static and linear dynamic (Response Spectrum Method)
