摘要
为提高建筑钢结构稳定性检测的准确率及其参数评估精度,提出基于阻尼耗能支撑模型的建筑钢结构抗震稳定性检测方法。首先分析地震作用下建筑钢结构的稳态特征,结合自复位阻尼耗能支撑约束条件下计算地震波的转移状态,在此基础上考虑阻尼力和耗散地震输入能量进行建筑钢结构抗震的量化评估。基于上述构建自恢复耗能支撑,分别计算阻尼耗能支撑的复位力和耗能参数,实现建筑钢结构抗震稳定性检测。仿真结果表明,采用该方法进行建筑钢结构抗震稳定性检测的准确性较高,参数评估的精度较好,具有很好的抗震稳定性检测能力,可为建筑施工的抗震性能分析提供理论基础。
In order to improve the detection accuracy of the building steel structure stability and its parameter evaluation accuracy,we put forward a method for detecting the anti-seismic stability of the building steel structure based on the damping energy dissipation support model.First,we analyzed the steady-state characteristics of the building steel structure under the earthquake.Second,we calculated the transfer state of the seismic wave under the self-reset damping energy dissipation support constraint condition.Last,on the basis of it,we conducted the quantitative evaluation of the earthquake resistance of the building steel structure by taking into account the damping force and the dissipation seismic input energy.Based on the built-up self-recovery energy-consuming support,we respectively calculated the restoring force and the energy consumption parameter of the damping energy-consuming support,and realized the anti-seismic stability detection of the building steel structure.The simulation results show that when this method is used in building steel structure detection,a higher detection accuracy,a better precision of parameter evaluation and a better ability in seismic stability detection can be achieved,thus it could provide a theoretical basis for the seismic performance analysis of building operations.
