RESEARCH ON THE APPLICATION OF ENERGY DISSIPATION AND DAMPING TECHNOLOGY IN SEISMIC DESIGN OF BUILDINGS

某医疗建设项目位于高烈度区域,易受地震影响。为确保建筑项目顺利并安全投入使用,采用消能减震进行建筑抗震优化设计。首先是分析项目消能减震目标,根据项目特征选择合适的消能减震技术方案,通过试验比较最终确定建筑消能减震方案。对候选两种方案进行试验分析,粘滞消能器方案在x向楼层间最大位移角为0.001 9度,优于金属屈服消能器。同时比较两种方案在不同地震下的楼层间剪切力情况,粘滞消能器方案表现最佳。研究内容为建筑项目抗震设计与结构优化提供技术参考。

A medical construction project is located in a high-intensity area and is susceptible to earthquakes.To ensure the smooth and safe operation of the construction project,energy dissipation and seismic reduction are adopted for seismic optimization design of the building.Firstly,analyze the energy dissipation and seismic reduction targets of the project,select appropriate energy dissipation and seismic reduction technology schemes based on project characteristics,and finally determine the building energy dissipation and seismic reduction scheme through experimental comparison.Experimental analysis was conducted on the two candidate schemes,and the viscous energy dissipation scheme had a maximum displacement angle of 0.0019 degrees between floors in the x-direction,which was superior to the metal yield energy dissipation scheme.Simultaneously comparing the shear forces between floors of two schemes under different earthquakes,the viscous energy dissipation scheme performed the best.The research content provides technical references for seismic design and structural optimization of building projects.
