Experimental Study On The Mechanical Behavior Of Light-weight & High-performance Concrete And Multi-ribbed Composite Wall

Multi-ribbed composite wall structure is a new energy-saving structure system, and has achieved staggered fruit on the theoretical investigation and application study. Multi-ribbed composite wall (MRCW) is the mainly mechanical component of the structure and uses autoclaved aerated concrete block as its filled wall material, which is used as shelter, mechanical component and heat-preservation at the same time.However, autoclaved aerated concrete block is always used as shelters and have little study on its mechanical behavior, especially, under the complex stress condition; furthermore, along with MRCW is acceptable, the economical and climate-resistant wall material is needed.To solve above problems, the thesis does these work below:1. Firstly, on the base of the investigation to the new wall materials domestic and overseas, the thesis compares the mechanical and physical performance of the material and adopts ones which is fit to MRCW.2. Through the mechanical behavior experiment of autoclaved aerated concrete block and foamed concrete block, the thesis gets the compressed strain-stress curves and suggests the equation of the compressed strain-stress curves.3. Based on the suggested equation of autoclaved aerated concrete block and foamed block, the thesis uses ANSYS to analyze the mechanical behavior of MRCW.
