Correct Design

In bridge design one of the main design criteria is fatigue. Better understanding, correlation and correct design rules are important to ensure safety. New code for the design of bridge structures made of aluminium alloys are being developed in Russian Federation. The authors tested a full scale pedestrian bridge for static and cyclic loading. The results of the experiment and numerical simulation are analyzed and presented in this article.

Seismic induced pounding damage to bridge structures was repeatedly observed in many previous major earthquakes. To avoid this adverse effect, extensive research efforts have been made by many researchers. This paper presents a state-of-the-art review in this field. It includes a brief review of the numerical modeling of bridge structures and impact models, numerical simulation of pounding responses between different components of bridge structures, experimental investigations, and pounding mitigation methods.

Bridge Bearing

A prototype of sensored bridge bearing was developed, fabricated, tested and planned to be applied in two bridge structures for sensing and monitoring of construction process and service condition. Besides, numerical modeling of the prototype was performed using the finite element method with ABAQUS, and meanwhile the testing results were calibrated. Numerical simulation results of the selected two bridge structures show that certain bearing reactions are sensitive to the interested behaviors and performances. This kind of sensored bearing is considered feasible for monitoring construction, damage scenario, and applied loads.

AbstractIn this work the attention is focused to the numerical simulation of the experimental bending tests carried out on a total of six reinforced concrete r.c. plates the latter aimed to provide a basic understanding of the its performance when strengthened by Fiber Reinforced Cementitius Matrix (FRCM) Composites. Three of those were used as control specimens. The numerical simulation was carried out by LUSAS software. A good correlation between the FE results and data obtained from the test, both in the load–deformation behavior and the failure load was highlighted. This permits to prove that applied strengthening system gives back an enhancement 2.5 times greater in respect of the unreinforced case. A greater energy dissipation ability and a residual load-bearing capacity makes the proposed system very useful in the retrofitting as well as in the case of strengthening of bridge structures. Based on the validation of the FE results in bending, the numerical analysis was also extended to characterize the behavior of this strengthening system in tensile.
