Title: Effect Of Frame Shape And Geometry On The Global Behavior Of Rigid And Hybrid Frame Under Earthquake Excitations
Author: Hoq, S.M. Ashfaqul
Abstract: The primary focus of this study is to present a shape which will improve building performance in earthquake excitations. The investigation started with 3-, 9-, 12- and 20-story rectangular frame. The seismic performance is observed for different earthquake data with different frequency content. Then, the Rhombus shape is introduced to compare with the Rectangular shape frames, keeping the height-to-width ratio and loading same. For the first part of the investigation, deflection and member forces are compared between rhombus and rectangular shape considering all connections rigid. In the second part of the study partially restrained connections are introduced in mid levels of the high rise frames to observe the redistribution pattern of internal forces. The results show that with all rigid connections, rhombus shape performs better than rectangular frame in most of the cases. Also, partially restrained connections which forms hybrid frame have more significant effect on rectangular frame than the rhombus frame.
