SEISMIC DYNAMIC ANALYSIS ON SLITTED SHEAR WALL STRUCTURE WITH HEAT PRESERVATION FORMWORK
The presentation of the slitted shear wall structure with the heat preservation formwork has blazed a new way in the development of energy saving building system. Based on the three-dimensional finite element model, the seismic dynamic analysis on the slitted shear wall structured building was conducted by using ANSYS software. The structural strength under the earthquake loading was checked by using a response spectrum method. The elastic deformation of the structure under the earthquake loading was calculated by using the time-history analytic method to find out the failure type of the structure. Meanwhile, the shear wall model was established to contrast with the experimental building structure model. The result shows that this new type of the structure can reduce its self-weight and frequency, and in turn, to moderate the structure reaction to earthquake. The elastic story drift was very slight in the case of frequently occurred earthquake, so the new structure has stronger stiffness and lesser lateral displacement, and also has stronger capacity of seismic resistance than the shear wall structure. The conclusions may be used as a reference for the safe, economical and applicable house design.
