选择安全、经济、实用的结构类型是结构设计的关键。通过对鄂尔多斯同基双子座项目办公楼工程采用混合结构与混凝土结构两个方案比较,结果表明混合结构虽然工程造价略有提高,但梁柱截面小,自重轻,实用面积大,抗震性能良好,施工速度快,且还可以进一步优化,综合效益更为显著,是未来超高层结构的发展方向。因此,工程最终选用了混合结构方案。
Choosing a safe, economical and practical type of structure is the key to structural design. The results show that although the cost of the hybrid structure is slightly increased, the cross section of the beam is small, the weight of the beam is small, the area of practical area is large, and the seismic performance is good. The construction of the composite structure is good. The construction of the project is similar to that of the concrete structure. Speed, and can be further optimized, the overall efficiency is more significant, is the future direction of the development of ultra-high-rise structure. Therefore, the project finally chose a hybrid structure program.
