A Review on Seismic Performance Analysis of High Rise Modular Steel Construction (MSC)
The construction industry has tried out a variety of trends in its field to bring out innovative, economic, efficient and sustainable infrastructure to meet the growing demand. One such development is the off-site manufactured modular steel buildings. The practice reduces the construction period as well as reduces wastage of resources. It was extensively used for low rise structures earlier, but due to increasing urban construction demand the practice is preferred nowadays in high rise structures too. For the high rise structures the lateral stability needed to be well looked into as there may arise a mass irregularity, structural irregularity, discontinuity etc. Psychological acceptance of such construction practice by the public is also not assured as they are not well aware of the advantages and use of the practice. And hence there is a need to conduct detailed and thorough investigation on its contradiction part to seismic performance. The modular construction consists of different structural systems and load transferring mechanisms. The integration of many materials and elements to modular structures are also discussed in various papers. But regarding lateral force resistance of its structural and non-structural components only limited research is conducted. Further research is required. The aim of the study is to provide a collective critical review on individual units or components of the structural system and their effects contributing to seismic resistance.
