This paper identifies assessment techniques for critical parameters relative to installation and performance of fiber reinforced polymer (FRP) materials as a way to strengthen structurally deficient concrete bridges. Various Nondestructive Testing (NDT) techniques, representing viable solutions for identification and monitoring of such critical parameters on structural members strengthened with...

To investigate the sensitivity of overall mechanical performance steel–concrete composite beam bridges (SCCBBs) to different types damage, this paper proposes a method analyzing SCCBBs damage based on extremely randomized trees (ET) algorithm in machine learning. A continuous bridge was used as engineering basis, and finite element analyze changes static dynamic response caused by seven damage....

In this paper, the effects of using semi-active control strategy (such as MR dampers) in vehicle suspensions on the coupled vibrations of a vehicle traversing a bridge are examined in order to develop various designs of smart suspension systems for bridge-friendly vehicles. The bridge-vehicle coupled system is modeled as a simply supported beam traversed by a two-degree-of-freedom quarter-car m...

Water leakage and debris accumulation caused by the expansion joints in a bridge superstructure reduce service life of increase maintenance costs. A link slab is an effective means to eliminate joints, providing continuous deck system. However, load-caused concrete cracking also leads problems associated with water rebar corrosion. In order solve these problems, new type steel–concrete composit...

Abstract A finite element numerical model is used to estimate the force displacement backbone curve of steel moment frame beam-column-joint subassemblies tested at large scale under repeated cyclic loading with different composite deck slab configurations. The configurations included: no-slab; fully isolated slab; two for detailing near region between column flanges; and a full depth reinforced...

Background: Bridge deck inspection is essential task to monitor the health of the bridges. Condition monitoring and timely implementation of maintenance and rehabilitation procedures are needed to reduce future costs associated with bridge management. A number of Nondestructive Evaluation (NDE) technologies are currently used in bridge deck inspection and evaluation, including impact-echo (IE),...

In the design of bridges with large spans, the significant values of the moments at the main deck-structure require very heavy members, either in the case of a beam or a truss deck-structure. In order to minimize the influence of bending moments, several applications of passive control of displacements using cable nets are herein proposed. The base for all the proposed systems is the cables sup...
