摘要: 宛平劇院屬于空間復雜的大型觀演類公共建筑,存在樓板大開洞、樓屋蓋大跨度等技術(shù)難點,同時需要滿足裝配式建筑的要求。 通過鋼結(jié)構(gòu)與混凝土結(jié)構(gòu)的分析論證,最終結(jié)構(gòu)主體采用鋼結(jié)構(gòu),并針對樓板大開洞、大跨度鋼結(jié)構(gòu)、大空間圍護結(jié)構(gòu)側(cè)向穩(wěn)定等難題提出了解決措施。 對結(jié)構(gòu)進行設(shè)置黏滯阻尼墻的阻尼方案與剛性方案進行對比分析,最終選擇鋼框架?中心支撐?黏滯阻尼墻體系。 通過設(shè)計優(yōu)化減小結(jié)構(gòu)剛度、增加結(jié)構(gòu)周期、提高阻尼比,有效地降低了地震作用,提高了結(jié)構(gòu)抗震性能,同時節(jié)省了用鋼量,降低了結(jié)構(gòu)造價。 采用 PERFORM?3D 軟件進行了結(jié)構(gòu)罕遇地震彈塑性時程分析,結(jié)果表明,黏滯阻尼墻在罕遇地震下能夠正常工作,耗能曲線飽滿,結(jié)構(gòu)滿足性能目標要求。

Abstract: Wanping Theater is a large?scale public building for performance with complex space. It has technical difficulties such as large openings in floors and large?span roofs. At the same time, it needs to meet the requirements of prefabricated buildings. Through the demonstration of steel structure and concrete structure, the final main structure adopts the steel structure,and the solutions were put forward according to the difficulties of large openings in floors, large?span steel structure and large space envelope lateral stability. According to the analysis and comparison between the viscous damping wall scheme and the rigid scheme, the steel frame central support viscous damping wall system was finally selected. Through design optimization, the stiffness of the structure was reduced, the period of the structure was increased, and the damping ratio was increased, which effectively reduces the seismic action, improves the seismic performance of the structure, saves the amount of steel and reduces the cost of the structure. The elastoplastic time history analysis of the structure under rare earthquake was carried out by using PERFORM?3D. The analysis results show that the viscous damping wall can work normally under rare earthquake, the energy dissipation curve is full, and the structure meets the performance target requirements.

Keywords:Wanping Theater; steel frame central support system; viscous damping wall; elastoplastic time history analysis
