摘要
避难建筑通常采用置换混凝土方法抗震,建筑对高强度地震的抗震性能差。因此提出高强度地震下带钢避难建筑抗震设计方法,采用复杂网络带钢避难建筑加固模型对加固前建筑的混泥土强度与荷载能力进行计算,增大框架柱截面,提升带钢避难建筑荷载。采用复合墙体受力加固模型提升建筑墙体抗震性。对加固后建筑模型的坍塌风险评估时,采用带钢避难建筑坍塌的全概率衡量加固后建筑在设计使用年限内的抗坍塌安全性。设计使用年限内加固后的带钢避难建筑的强震CRC超出概率是P(IM>CRC),确保其在高强度地震下具有较高的抗震性能。实验结果说明,所提方法下的带钢避难建筑在遇到强震情况时具有较高的抗震性能。
Refuge buildings often adopt the concrete replacement method to resist earthquakes, which results in a poor seismic performance when the buildings are subjected to strong earth quakes. Therefore, this study investigates the aseismic design method for steel strip refuge build ings under strong earthquakes. A complex network strip steel refuge building reinforcement model was adopted to calculate the strength and load capacity of a reinforced concrete before rein forcement. The section of the frame column was enlarged, and the load of the refuge building was increased. The earthquake resistance of the building wall was improved by a composite wall rein forcement model. When evaluating the collapse risk assessment of the reinforced building model,safety of the performance o when subjecte collapse of steel s during its design trip refuge building was used to life. The experimental results show the coll the sei f steel strip refuge buildings designed with the proposed method is relatively d to strong earthquakes.
