网壳筒体-混凝土芯筒结构的设计方法研究

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。

Design Method Research into Latticed Shell Tube-Reinforced Concrete (RC) Core Wall Structures

Latticed shell tube-RC core walls are a new structural system with RC core walls in the center and latticed shell tubing on the outsides.The shear rigidity of RC core wall is big,and the resisting overthrow capability of external latticed shell tubes is powerful.This combination can reduce structural damage that could be caused by seism,and it remarkably enhances the anti-seismic capability of structures.The basic design procedure for constructing these structures is introduced sequentially,particularly poi...
