摘要:
青岛邮轮母港客运中心钢屋盖的多根异形变截面杆件通过焊接直接汇交于节点,杆件尺寸大,构造复杂,属于复杂空间节点.以初步设计的节点为研究对象,利用ABAQUS有限元软件对典型的复杂空间节点建立了有限元模型,并进行了静力分析,研究节点在最不利荷载工况作用下的受力性能及破坏机理.结果表明:在最不利荷载工况下,虽然杆件的应力保持在屈服强度内,但节点核心的最大应力超过了屈服强度.本设计通过增加核心区板件厚度30%解决了节点核心应力过大的问题,可为工程中此类节点的设计优化提供参考.
Abstract:
The steel roof structure of the Passenger Transportation Center of Qingdao Packet Ship Base has many special-shaped and variable cross-section members which are welded directly to each other at most joints. The joints are complex space joint because their dimension is large and the geometrical construction of members is complex. The preliminary design of the joints were used as the research object the finite element model of typical complex spatial joints were established with the FE software ABAQUS and the static analysis was conducted. The results show that the stress of members is within the yield strength but the problem is that the maximum stress of joint core area is greater than the yield strength under most load cases. The problem was solved by increasing the thickness of joint core plate, which can give a reference to design of other projects.
