网壳筒体-混凝土芯筒是一种新的结构体系,混凝土芯筒在中心,网壳筒体在外面。混凝土芯筒的剪切刚度大,外部网壳筒体抗倾覆能力也很大,这种组合能减少地震造成的结构损坏,显著提高结构的抗震能力。介绍了构建这种结构的基本设计程序,特别指出了设计的关键问题。进行了综合的结构分析,全面评估了新结构形式的性能。提出了评估这种结构的新的实用方法,采用等价杆系模型近似地模拟钢筋混凝土剪力墙和板,通过调整弹性模量和材料的密度,使其与现有的结构具有相近的整体刚度和质量。最后,通过工程验证了相关的设计方法,证明对于高层建筑设计这是一个合适的方法。
Reticulated shell - concrete core barrel is a new structural system, concrete core in the center, the outer shell of the shell. The shear rigidity of concrete core barrel is large, and the anti-overturning capability of the outer shell is also great. This combination can reduce the structural damage caused by the earthquake and significantly improve the seismic capacity of the structure. The basic design procedure for building this structure is presented, with particular reference to the key design issues. Conducted a comprehensive structural analysis, a comprehensive assessment of the new structure of the performance. A new practical method to evaluate this structure is proposed. The equivalent rod model is used to approximate the RC shear wall and slab. By adjusting the elastic modulus and the density of the material, the structure is similar to the existing structure Stiffness and quality. Finally, the relevant design method was verified through engineering, which proves that this is a suitable method for high-rise building design.
