The Formulation and Experimental Verification of Mathematical Models for Predicting Dynamic Response of Multistory Buildings.

摘要

In the design of multistory buildings for lateral loads,the use of mathematical models to predict dynamic response has become an accepted practice. However,the accuracy of the predictions depends primarily on whether the model is formulated correctly for representing characteristics of the actual building. Currently,this formulation is not necessarily a straightforward,well defined process,but depends largely on engineering intuition and experience. This paper surveys the problems experienced in formulation of math models for actual buildings in the past, deduces from these studies suggested modeling guidelines based on success or failure of models investigated. Having proposed guidelines for different types of buildings, a study was made for a 15-story steel frame apartment building in Cambridge,Mass.
