以高速铁路中采用的圆端形空心桥墩为原型, 设计了10 根大比例模型. 考虑恒定轴向力的作用,
进行低周反复荷载试验, 得到不同桥墩模型的破坏特性, 滞回曲线, 依此分析各参数下桥墩的延性 …

分析了中国6 座大型铁路桥梁和26 座大型公路桥梁中空心桥墩的设计情况, 从墩高, 壁厚比,
薄壁宽厚比和剪跨比等方面对空心桥墩在中国的应用情况进行了评述. 总结了新西兰, 美国 …

Although many in-situ RC beams are of continuous constructions, there has been very little
research on the behavior of such beams with external reinforcement. This article presents an …

The influence of shape memory alloy (SMA) reinforcement on the non-linear static and
dynamic responses of hollow-section concrete columns to earthquakes was investigated …

Continuous unbonded posttensioned concrete beams might require strengthening to cope
with higher demands. Strengthening with carbon-fiber-reinforced plastics (CFRP) is a viable …

Reinforced concrete (RC) hollow piers in bridges withstand high moment and shear
demands ensured with reduced mass and lower stress on foundations compared with solid …

This study investigated the behavior of hollow concrete columns (HCCs) reinforced with
glassfiber-reinforced polymer (GFRP) bars and spirals under axial loading. Nine columns …

Seismic behavior of reinforced concrete hollow rectangular bridge columns retrofitted with
carbon fiber reinforced polymer (CFRP) was carried out under constant axial loading and …

This article describes the finite element analysis of concrete columns with a hollow square
reinforced which restricted with a square Carbon-Fiber-Reinforced polymer (CFRP) tube. In …

Abstract an investigation was conducted to identify the behavior of steel fiber reinforced
concrete columns with an opening under eccentricity loading, focusing on square hollow …
