| Tibetan building is easy to use local materials,it has to adapt to the local climate and environment,in line with the local residents living habits,with a strong ethnic characteristics of religion and regional characteristics.Research found that the region’s stone-wood structure housing construction quality is mixed,mostly adopt effective measures in the construction of the stone wall compressive performance is poorer.To find suitable measures for the practice of local housing construction and meet the wall design method of the compressive performance requirements,this paper adopted the Tibetan areas of gravel caulking and construction method to control the proportion of unilateral variation in thickness,six groups of different condition of stone masonry wall specimens,stone wall compressive performance experiment was carried out.Study the compressive performance of this kind of stone wall,analysis of the effect of the structural measures in the compressive performance of the stone wall,and on this basis,to provide some Suggestions for design and c onstruction reference.In this paper,the main research contents and research results are as follows:(1)Compression test was carried out on the stone wall and observe the damage form of structure under vertical load at all levels,analysis the weak position of the stone wall,test the compressive capacity of stone walls in this kind of structural measures.(2)Analysis the displacement and strain of the structure under vertical load,make the study of the stress distribution and the change of the power transmission path in the stone wall under different vertical load;analysis deformation performance of stone wall under different working conditions;analysis compressive performance of the stone wall in different construction measures.(3)According to the test results to evaluate the compressive properties of the stone wall in gravel caulking and unilateral variation in thickness,it is concluded that such use gravel caulking and reasonable construction measures to control the proportion of unilateral variation in thickness can significantly increase the compressive performance of the stone wall.(4)According to the test results and analysis the deformation properties and stress distribution and load transformation path,give the suggestions to the actual structure design and construction design of the stone wall,improve the compressive performance of stone-wood structure building.This article research results give the effective basis to the structure and construction design in Tibet region stone-wood structure building,also can provide reference for the writing of the relevant specification. |
