重庆西南大学附属中学体育馆是综合性的体育馆。根据建筑的平面跨度,通过张弦梁、带肋结构、立体桁架等多种方案的比选,屋面最终选择了简洁美观、易于施工的空间网格结构,该结构形式用钢量最小并完全能够满足屋面的受力性能的要求。为满足建筑立面效果,本工程的主要竖向构件采用了人字形钢柱,钢柱下采用桩基,通过计算分析,人字形钢柱能够满足竖向和水平承载要求。此外,对本工程还进行了抗震性能化设计,同时在大震弹塑性时程分析的基础上,明确了结构在大震下的薄弱部位和损伤情况,并据此进行有效的设计,保证了结构体系的合理性及可靠性。
Chongqing Southwest University Affiliated High School Gymnasium is a comprehensive gymnasium. According to the plane span of the building, through the comparison and selection of various schemes such as string chord, ribbed structure and three-dimensional truss, the roof is finally selected with a simple and beautiful space grid structure which is easy to construct. The requirements of the force performance. In order to meet the effect of building facades, the main vertical component of the project uses herringbone steel columns and piles under steel columns. Through calculation and analysis, the herringbone columns can meet the vertical and horizontal bearing requirements. In addition, the seismic performance design of the project was also carried out. Based on the elasto-plastic time history analysis of the large earthquake, the weak parts and damages under the earthquake were clarified and effective design was carried out to ensure the structure System rationality and reliability.
