STAGED CONSTRUCTION ANALYSIS FOR HIGH RISED BUILDING WITH SEISMIC ANALYSIS

While analyzing high rise structure in Conventional method the gravity loads are applied after modeling the whole structure. In actual practice the complete frames are constructed at various stages and the stability of frames varies accordingly. The applied load assumed in Conventional method will be unsuitable as per the actual construction practice. The frame should be analyzed at every construction stage considering the effect of variation of loads at each stage. This methodology is known as construction sequential analysis. In this project the realistic structure of G+11 and G+14 in seismic zone IV as per IS 1893:2016 (Part 1) considered to study the effect of construction sequence. Tall building of three different heights has been considered for comparative study and effect on columns and beams has been studied based on different structural parameters. Based on study the necessity of the construction sequence analysis for tall building has been understood.
