Bearing Capacity Analysis Of Expansive Polystyrene Granule Cement(EPSC) Latticed Concrete Wall Exposed To Fire Form One Side

With the environmental pollution and lack of energy which increasingly affects the human's life,advanced technology of expansive polystyrene granule cement(EPSC)latticed concrete wall,which is maturely developed in foreign countries,can fully conform to the requirement of environmental protection and energy saving thanks to its advantages such as light weighting,environmental protecting,recycling,energy saving,thermal insulating and speed constructing EPSC latticed concrete wall is a new type of structural system original from Europe,by assembling prefabricated EPSC boards in site with reinforced self-consolidating concrete inside.With the development of EPSC latticed concrete wall in China,it will certainly be widely used in the future.The bearing capacity at high temperature is firstly obtained by analyzing the temperature distribution in the EPSC latticed concrete wall with aide of the temperature field calculation by finite element analysis software.The distribution of bearing capacity in the wall is then acquired by measuring the bearing capacity of the latticed columns in different locations in the wall.A comparison of temperature field is also conducted between EPSC latticed concrete wall and traditional concrete wall with the same dimension in terms of time at fire.In addition,a parameter analysis of reinforcement ratio is carried out under room temperature and high temperature.Finally,the influence of non-uniformly distributed load to the deformation of the wall is clarified by applying this load to EPSC latticed concrete wall under room temperature and high temperature.
