摘要
某美术馆建于1994年,因使用需要,拟续建一层并进行修缮改造。在房屋结构质量鉴定和抗震计算分析基础上,决定采用改变结构体系的加固方案。在适当位置增设混凝土剪力墙,通过调整剪力墙位置及刚度减小扭转效应。对梁柱也采取了加固措施,确保了新旧体系共同工作。
An art museum,built in 1994,is planned to be heightened by one more storey due to functional requirements and to be repaired and rebuilt.Based on quality inspection of the building structure,aseismic calculation and analysis,it is determined to adopt the reinforcement scheme of changing the structural system.Concrete shear wall is set at appropriate position,and twisting effect is reduced through adjustment of the shear wall position and stiffness.Reinforcing measures are also adopted for the beam column to ensure the cooperation between the new and old systems.
