A Finite Element (FE) model which can precisely predict the actual dynamic responses of a bridge is necessary for accurate condition assessment and health monitoring purposes. However, most of the bridge FE models initially developed for design purposes may not be...

G. W. van der Linden, A. Emami-Naeini, R .L. Kosut, H. Sedarat, and J. P. Lynch In this paper we focus on comparing three candidate approaches to the optimal placement of sensors for state estimation-based continuous health monitoring of structures. The first aims to...

The lateral behavior and stability of bridge column rebar cages were investigated to reduce the potential of failure and collapse during construction. Rebar cages are temporary structures made of longitudinal and transverse reinforcing bars that are connected by tie...

Caltrans’ Toll Bridge Seismic Retrofit Program involved performing vulnerability assessments and retrofit designs for the state-owned toll bridges. To determine bridge response and evaluate seismic performance, a finite element model of each toll bridge was created...

In the current state-of-practice of the performance-based design of structures, simplified procedures are often used to evaluate the deformation capacity of structural systems. One specific example is using the rotation limits for the deformation-controlled elements....
