Validation of Simplified Procedures for Predicting Global Response in the Context of DBD of Bridges, Including the Flexibility of Foundations / Case Study Comparison of DBD Iterative Procedures for Bridges

Abstract

The present report collects the work performed in Deliverable 112 "Validation of simplified procedures for predicting global response in the context of DBD of bridges, including the flexibility of foundations" and in the chapter corresponding to Displacement Based Design of Deliverable 113 "Case study comparison of DBD iterative procedures for bridges" of the LESSLOSS Project, dealing with three main subjects: verifying that the concept of the Substitute Structure constitutes a valid means of predicting the response of a bridge structure undergoing plastic deformations; formulating a procedure for the displacement based design performance of bridges; defining the parameters of a Takeda Model to be used within the context of non-linear time history analysis of bridges with RC rectangular hollow columns.
