An innovative lateral force resisting system is investigated that allows steel braced frames to uplift and rock on their foundation, partially isolating the frame. Passive energy dissipation devices are implemented at the uplifting location to control the rocking response to within allowable limits. The structure’s gravitational forces provide an inherent restoring force during the rocking resp...

The objective of this research project is to examine the use of FRP materials for bridge construction. In particular, this project utilizes glass FRP (GFRP) honeycomb sandwich panels. The installation of three bridges, one comprised solely of the FRP panels and two comprised of the FRP panels supported by steel girders, is outlined. Furthermore, results of preliminary testing conducted on the F...

With advances in sensor technology and availability of low cost integrated circuits, a wireless monitoring sensor network has been considered to be the new generation technology for structural health monitoring. Wireless Intelligent Sensor and Actuator Network (WISAN) has hence been developed as a vibration based structural monitoring network that allows extraction of mode shapes from output-on...

One of the most commonly discussed problems regarding bridges with integral abutments is the influence of longitudinal elongation of the superstructure as a result of seasonal temperature variations. A bridge built with integral abutments is often supported by a row of piles made of steel or concrete. The longitudinal elongation of the superstructure induces a displacement and a rotation at the...

The Analytical Hierarchy Process was used to characterize the bridge material selection decisions of highway engineers and local highway officials across the United States. State Department of Transportation engineers, private consulting engineers, and local highway officials were personally interviewed in Mississippi, Virginia, Washington, and Wisconsin to identify how various factors determin...

The bridge is a road-complementary structure that functions to connect two ends of the road crossed by rivers, canals, valleys, seas, highways, and railroads. A truss made combining steel elements according design criteria binding technical aspects. Citanduy Bridge located in Ancol Village, Cineam District, Tasikmalaya Regency, West Java. This has been operated, determine capacity bridge, will ...

The concept of designing sacrificial elements to dissipate seismic energy while preserving the integrity of the structure’s other main components is known as the structural fuse concept. Few implementations of the structural fuse concept have been rigorous in emphasizing easy and complete replaceability of the sacrificial elements and absence of damage to the primary load-resisting structural s...

To implement steel bridge maintenance, especially that related to fatigue damage, it is important to monitor bridge deformations under traffic conditions. Bridges deform and rotate differently under traffic load conditions because their structures differ in terms of length and flexibility. Such monitoring enables the identification of the cause of stress concentrations that cause fatigue damage...
