Research And Application Of The EPS Module With Reinforced Concrete Frame Structure

The EPS module with reinforced concrete frame structure of building energy saving system a new type of structural system.With EPS module for concrete undismantled emplate achieved integration bearing and insulation.The column reinforcement connected with Foundation beam reinforcement and Frame beam reinforcement,floor slab reinforcement embedded in Frame beam reinforcement Ultimately form an integral frame structure reinforcement bar structure.In conjunction with the pouring of concrete,until the concrete condensation sclerosis and closely occlusal the surface of the module,thus forming a new structure system integration bearing and thermal insulation.The system has advantages of tightness,insulation joint, to avoid demolition template, quick construction and installation, energy saving, etc., The system has important practical value and broad application prospects for reconstruction,transformation mud thatched cottage in rural,construction of low-rise energy-saving houses in earthquake-proof district.The EPS module with reinforced concrete frame structure system started late in our country,especially the research on its seismic performance is not very full, this article uses the finite element analysis software ABAQUS carries on the study of the seismic performance, the results are as follows:(1)According to “Technical Specification of EPS Module with Reinforced Concrete Frame Structure” and “Code for design of concrete structures”design of the three layer EPS model with reinforced concrete frame structure housing. To provide a model for the analysis of finite element.(2)Establishment finite element model of reinforced concrete frame, the EPS module with reinforced concrete frame and the EPS module with recycled concrete frame.According to the modal analysis and comparison of the two vibration characteristics and mode shapes. EPS module framework has stronger resistance to torsional compared to reinforced concrete framework.(3)Dynamic time history analysis of Model I 、 II 、 III,based on analysis andcomparison of acceleration time history curve,displacement time history curve,the largest story displacement and story drift angle,we can see that the EPS module frame structure seismic performance is better than the frame structure.Further validate the practical value of the EPS module with reinforced concrete frame structure system.(4)Made the thermal performance calculation for EPS module with reinforced concrete frame structure system.
