About this document
Two-Stage Analysis for Flexible Structures by Vũ Ngọc Thịnh is a document available to read on EtoBox.
The document discusses a two-stage analysis procedure for seismic design of structures with flexible upper portions and rigid lower base structures according to ASCE 7-10. The procedure treats the upper and lower portions as separate structures to simplify design. Key requirements are that the lower section be 10 times stiffer than the upper, the total structure period be within 10% of the upper portion alone, and each portion be designed using appropriate R and rho values. Forces from the upper portion amp
