摘要
Abstract
The China Resources Headquarter Tower with building height of 400 m is like a bamboo shoots in spring.It has a tube-in-tube structure system,and the external steel tube consists of inclining columns.So,many complex multi-column crossing joints are coming to fit the building shape.The process of design and verification of the bottom multi-column crossing joint is introduced to start with the path of force transmission.Connection scheme of joint slabs,slab thickness optimization and detail construction are also recommended.Usually,the joint will be simplified so that machining and setting up can be more easily.However,this simplified process may produce additional force to the joint.Flatting the joints panel might bring a secondary stress up to 40％ of the initial stress,as extra moment exists.Its influence cannot be iguored.The verification test resuhs show that the finite element analysis results are consistent with that of the test,and the joint designed reasonably will be elastic under the design load.Comprehensive analysis of the force transfer path and the constructional details is conducted to ensure the structure safe.关键词
