Research On Static Test And Finite Element Analysis For Rick Husk And Mortar Composite Wall Panels

This thesis provides an overview of the current domestic and foreign buildingenergy efficiency forms and policies, a detailed description of the variousenergy-saving building materials, and the contrastive analysis between theadvantages and disadvantages. It focuses on the static test of a new type of energysaving wall material rice husk mortar energy-saving composite wall.Rice husk mortar compound wall is composed of mortar and steel mesh fromthe husk framework composition, composited with energy-saving materials, factoryprefabricated, site installed. This kind of wallboard not only facilitates theconstruction, saves the template works expenditure, shortens the construction time,but also meets the ecological environment protection and energy-saving emissionreduction requirements. This type of wallboard with energy saving andenvironmental protection characteristics, can be recycled and installed industrially,also used as a building filled with non-load bearing exterior wall. And this kind ofwallboard has already become a certified energy-saving product in HeilongjiangProvince.This thesis’s main contents are as follows:(1) In order to determine the material property of rick husk and mortarcomposite wall, ease the finite element analysis, this thesis carried out the propertytest of rick husk and mortar test block on50tons pressure machine in the structuraltest department of Harbin Institute of Technology.(2) This thesis conducts a full-scale specimen experiment on none-opening ricehusk mortar compound wall in the structural test department of HeilongjiangTechnology University. The loading process is divided into two phases, the load stepis4kN. The phenomena is observed and relevant experimental data is extracted.(3) This thesis carried out the non-opening rick husk and mortar compositewall’s finite element analysis. And compared the results with the test results,validated the finite element model’s correctness. Studied the wallboard’s mechanicalcharacteristics.(4) The finite element analysis on different wall-opening kinds of rice huskmortar compound wall concludes that, the mechanical behavior of the wallboards isaffected by the size and location of the wall-openings. The bigger the size and themore eccentric the location is, the lower the wallboard’s mechanical behavior is.(5) Through the above analysis, this thesis validated the relationship of loadand strain energy, obtained the relationship between the wallboard’s mechanicalbehavior and the size and location of the wall-openings.
