Controlled rocking of steel braced frames has been proposed for the seismic retrofit of structures. The controlled rocking approach allows a frame to uplift from its support at the base-of-column to foundation interface while displacementbased steel yielding devices are implemented at the base location to control the response. Past studies have focused on analytical investigations of the respon...

In a laterally asymmetric intake pumping station, the flow direction in forebay is not consistent with channel. Thus, adverse patterns, such as bias flow, large-scale vortex and occur frequently sump. Based on Reynolds-averaged Navier-Stokes (RANS) equation RNG k-ε turbulence model, recent pattern station was numerically simulated analyzed, effective elimination measures were proposed. For orig...

The hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier were researched. The effects of the prestressed tendon ratio, the longitudinal reinforcement ratio, and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method. The analysis show...

Abstract The study of scouring around bridge piers is very significant and plays a important role in the safe economical design piers. term process by which bed particles periphery pier get eroded removed over certain depth resulting formation scour hole This paper presents detailed investigation local six different shapes namely rectangular, circular, chamfered, joukowsky, oblong, sharp-nosed ...

Original scientific paper The objectives of this paper are to perform a comparative analysis of the large-scale system of a high-pier railway bridge subjected to stationary and nonstationary spatially varying earthquake excitations using the pseudo-excitation method (PEM), and to estimate whether or not the non-stationary stochastic analysis of the high-pier railway bridges under tri-directiona...

Local scour around bridge piers and abutments is one of the most significant causes failure. Despite a plethora studies on individual or abutments, few have focused joint impact pier an abutment in proximity to another scour. This study conducted laboratory experiments flow analyses examine interaction their effect clear-water The were rectangular flume. They included 18 main tests (with combin...
