摘要

以某非对称双塔连体超高层结构为研究对象，选取与建筑所在场地相匹配的地震波作为激励，通过对结构进行非线性动力时程分析，研究混合消能减震连体结构在各烈度地震作用下的消能减震效果，探讨了屈曲约束支撑(buckling-restrained brace, BRB)与黏滞阻尼悬臂桁架的位置变化对结构抗震性能的影响，同时对结构进行了全面的抗震性能评估。研究结果表明：在连体结构中、上部的加强层中布设阻尼器时，结构具有更佳的减震效果；在不同水准地震作用下，BRB与黏滞阻尼悬臂桁架耗能阶段不同且具有不同的耗能效率，混合消能减震技术可以综合不同类型阻尼器的优势作用，使连体结构具有更全面的抗震性能。在控制变形方面，其能够降低连体结构的扭转效应和层间位移角；在构件耗能方面，其减轻了主体构件进入塑性的程度，降低了结构主要受力构件的应力水平。将为混合消能减震技术在连体超高层结构中的进一步研究和应用提供借鉴。

Abstract

An asymmetrical twin-tower connected super high-rise structure was studied here and the seismic wave matching the building's site conditions was chosen as the excitation. The non-linear dynamic time analysis of the structure was used to study the energy dissipation and damping effect of the hybrid energy dissipation and damping connected structure under the action of various intensity earthquakes. The influences of the position change of BRB and cantilever truss with viscous dampers on structural aseismic performances were discussed. Moreover, the energy dissipation and damage assessments of the entire tower were studied and discussed in detail. The results show that the structure has better damping effect when the damper is arranged in the strengthened story in the middle and upper part of the connected structure. Under different seismic levels, BRB and cantilever truss with viscous dampers dissipate energy in stages and have different energy efficiency, the hybrid energy dissipation and damping technology can integrate the advantages of different types of dampers, so that the connected structure has a more comprehensive seismic performance. In terms of deformation control, hybrid energy dissipation and damping technology can reduce the torsional effect and inter-story drift ratio of the connected structure. In terms of member energy dissipation, it reduces the degree of plasticity of the main members and lowers the stress level of the structure's main stress-bearing members. The results provided a reference for further research and application of hybrid energy dissipation and damping technology in connected super high-rise structures.
