偏心支撑钢框架常用于中震和强震地区的抗震结构和下部结构中。对这种结构的性能评估集中于修复损失和工作中断,而不是依据ASCE41检查构件。采用脆性函数,建立破坏阀值的可能性与效率响应(要求)参数的联系。脆性函数针对偏心支撑框架的连梁,可使性能评估与结构组件相结合。建立连梁剪切和弯曲临界状态下的数据。通过检查和统计试验数据,建立函数,并以连接的塑性转角为要求参数,采用破坏状态和修复方法解释试验数据。通过试验观察,确定最接近的破坏状态和相应的修复方法。在许多例子里,以钢组件破坏的直接指标描绘破坏状态,如腹板和翼缘的局部屈曲和断裂。通过4种修复方法关联每个破坏状态,依次为:修复损失(也称外观修复),混凝土更换,热矫直,连接更换。为偏心支撑框架连梁提供了破坏函数的一个有序序列。
Eccentric support steel frame is commonly used in earthquake-resistant structures and substructure in the areas of moderate and strong earthquakes. The evaluation of the performance of this structure has focused on repairing losses and disruptions rather than checking the components according to ASCE41. The use of brittleness functions establishes the link between the probability of destroying the threshold and the efficiency response (requirement) parameter. Brittleness Function The coupling beam for the eccentric support frame allows performance evaluation to be combined with structural components. Establish the beam shear and bending critical data. By checking and counting the experimental data, the function is established and the plastic corner of the connection is used as the required parameter to explain the test data by using the failure state and the repair method. Through the experimental observation, determine the closest damage status and the corresponding repair methods. In many cases, the failure indicators, such as local buckling and fracture of webs and flanges, are characterized by direct indicators of steel component failure. Through four kinds of repair methods associated with each damage state, followed by: repair loss (also known as appearance repair), concrete replacement, hot straightening, connection replacement. An ordered sequence of damage functions is provided for the eccentric support beam.
