大连国际会议中心复杂空间节点设计与有限元分析

Design and finite element analysis for complex spatial joints of Dalian International Conference Center

当前新颖奇特、造型别致的现代建筑不断涌现,为实现这些建筑效果,往往需要设计复杂的空间结构方案,从而导致结构设计和节点设计的难度增大,尤其是复杂空间节点设计难度更大.如何设计形式各异的复杂空间节点,满足建筑和结构安全可靠,成为结构设计者必须解决的问题.本文就大连国际会议中心工程对复杂空间结构中出现的复杂空间节点的设计方法进行了论述,从结构优化设计的角度总结复杂节点的设计思路和方法,并对复杂节点进行有限元分析,以了解复杂空间节点的受力状态并验证复杂节点设计的安全可靠.

Novel and unique modern buildings have been coming forth continuously in recent years.To achieve the architectural effect,complex spatial structural schemes are needed,which increases the difficulty in structure and joint design,especially for spatial joints design.How to design the complex spatial joints to meet the requirements of safety and reliability has become a problem that must be solved to a desiger.Methods of design for complex spatial joints in Dalian International Conference Center are discussed in this article.The main idea and method of complex design are summed up from the perspective of optimum structural design.FEM analysis are also carried out to know the status of the joints with combined load cases and the safety of the design of them.
