建筑在强震下横拉承压力钢筋负荷测量

Load Measurement of Building Steel Bars Subjected to Lateral Pressure and Strong Earthquakes

摘要:

在强震状态下，建筑物的横拉承压受力较为复杂，另外由于建筑物形状及在地震中受力面积大小不同，在强震下造成碰撞大小影响不一导致其横拉承压力的随机复杂性十分突出。传统的建筑承压负荷检测方法中钢筋负荷受力测量能力不足，检测结果易出现误差。将建筑钢筋的机械性能设为理想弹塑性，利用建筑物横拉承压力钢筋负荷测量方法，对不同结构、不同工况的建筑钢筋载荷的变化规律进行测试分析，结合建筑局部承压特点和整体结构聚力方式，设计横拉承压力钢筋负荷检测方法，并进行仿真实验，结果表明该方法模型所得数据更加精准，有良好的适用性。

Abstract:

In strong earthquake environments, buildings are subjected to complicated lateral pressure force. In addition, given the different shapes of buildings and different sizes of force-bearing areas under earthquake conditions, strong earthquakes cause different impact sizes. This difference results in the stochastic complexity of lateral pressure. The traditional method for the detection of building pressure load has insufficient measurement ability for steel-bar load force and provides detection results that are prone to error. A method for the measurement of load on building steel bars under lateral pressure is proposed. The load variation characteristics of steel bars with different structures are tested and analyzed under the ideal elastic-plastic condition of the mechanical properties of the steel bars and different load conditions. Combined with the local pressure characteristics of the building, the method for the measurement of load on building steel bars under lateral pressure is designed and subjected to simulations. Results prove that the proposed method provides data with improved accuracy and has improved applicability.
