Irregular Structural System Analysis And Methods

The method of thinking for irregular systems is that we should analyze them from various angles and in many considerations. It's hard to accomplish the designing of irregular seismic structures in real engineering practice if only following the current code according to the present technique level. This paper conducts a systematic analysis of irregular structural systems, especially of anti-seismic capability, respectively analyzing the scheme designing and the results of designing calculation for the irregular structure of a church and that with transformation floors, discussing the effect of irregular structural systems on the seismic reaction of architectural structures. The paper mainly analyzes the different influences of structural lay-out of irregular systems on structural stressing. When designing the architectural structures of irregular structural systems, no matter whether to consider them from use function or from security and economy, we should all properly select the position and form of the lay-out for irregular structures. In the designing of irregular structures, we should reasonably select the seismic design parameter and build up the model of structural mechanics that fits the real stressing state, and in the meanwhile, we should fully consider floor elastic deformation caused by the influence of plane irregularity of the building on plane stiffness.The work of this is embodied in the following aspects.1. Adopting the design plan of the double transfer floors in the ways of the irregular transfer floors with the bar arrangement column. It not only solves the construction plan of the uncontinuous frame column in definite degrees, but also gives some essentials about the design consideration.2. Geting the position of stress revulsion when shell is made holes through the design software sap2000 that is designed according to the shell texture, and raise the design plan about the edg of holes.3. To the irregular system of the transfer floors with high position, the thesis detailed analyzes the weak position when texture is high position transferring by four models, and according to the analyzing result, extend the change of the transfer floors character to the texture.
