Experimental Research And Finite-element Analysis On The Performance Of Rapid Wall Filled With Concrete Under Eccentric Axial Load

Many countries have begun the revolution of the wall materials from 1920sto 1930s, and the wall materials were impeled to be environmental protected.The common bricks are also prohibited and new wall materials products areadvocated in our country. The appearance of the rapid wall caters for thedemands of new times, since it has many advantages when applied in buildings.It has amplitude foreground in application. In this paper, the performance of the rapid wall with concrete filled undereccentric axial load will be tested. There are three kind of test specimens withthe total number is seven. They are filled with concrete every one, two or threeholes separately, and the eccentricity is 20mm or 30mm.Some discussions of thecapacity of pressing force and failed characteristics are shown. Besides, byusing nonlinear finite-element method, this article will make a practicalmechanic analysis model and analyse the specimens of the test.The results of theanalysis will contrast with the results of the test. The research results shows that the failure mode of the test specimens isbuckling and the capacity of pressing force of the rapid wall with concrete filledone or more holes(less than three holes) is enough for the tier buildings. Theresults of the theoretical analysis inosculate well with the results of the test.
