Modern building seismic reinforcement design method based on structural performance
The invention discloses a modern building seismic reinforcement design method based on structural performance, and belongs to the technical field of civil engineering seismic reinforcement. The methodcomprises the following steps that 1, the position of a TRC damper is determined; 2, the area of a viscoelastic body of the TRC damper is selected, and the equivalent rigidity and the equivalent damping coefficient of the TRC damper are calculated; 3, a seismic wave is selected to carry out elastic time history analysis, and a maximum displacement angle control target of a concrete frame structure is given under different damage states; 4, the shear damping rate, the modal damping energy consumption, the TRC damper energy consumption and effective damping ratio technical parameters added to the structure by the TRC damper are obtained according to the minimum viscoelastic body area; and 5, a beam column component in an energy dissipation substructure is subjected to steel-encased reinforcement. Compared with a traditional reinforcing mode, the method has the advantages that intervention on modern buildings is small, reversibility is achieved, and engineering design can be directly guided through optimization results.
本发明公开了一种基于结构性能化的近现代建筑抗震加固设计方法，属于土木工程抗震加固技术领域。包括以下几个步骤：步骤一：确定TRC阻尼器的位置；步骤二：选定TRC阻尼器粘弹性体面积、计算TRC阻尼器的等效刚度及等效阻尼系数；步骤三：选用一条地震波进行弹性时程分析，给出不同破坏状态下，混凝土框架结构最大位移角控制目标；步骤四：由最小粘弹性体面积得出剪力减震率、模态阻尼耗能、TRC阻尼器耗能及TRC阻尼器附加给结构的有效阻尼比技术参数；步骤五：对消能子结构中梁柱构件进行外包钢加固。本发明相比传统加固方式，对近现代建筑干预小，可逆，优化结果可直接指导工程设计。
