The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

This paper proposes an innovative method for determining the approximate incremental dynamic analysis curves of semi-isolated bridges, including derivation statistical mathematical formulas. Ultimately, is devised based on primary and limit state tangential stiffness values bridges. The bridges selected this study are two reinforced concrete highway in United States, which have been optimally r...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

The robustness of a structural systems is understood as their ability to prevent or reduce the consequences local (exceptional and/or extreme) event. current work aims address issues related evaluation structures with incorporated damage. case study an existing reinforced concrete arch bridge investigated in terms considering variation both cracking state from spalling and corrosion reinforceme...

When earthquakes occur, structures sustain damages. But it is impossible to estimate damages exactly which occur in the structures because of the uncertainty of materials and ground motions. Therefore, probabilistic methods for estimating damages of the structures have been suggested lately. In this study, probabilistic capacity spectrum method expanding established capacity spectrum method is ...
