Research On Seismic Behavior Of Composite Structure Of The Self Thermal Insulation Block Restrained Masonry

With the development, scientific progress, people gradually began to "greenenergy" to move closer to the concept of development, the construction industry in themasonry material from the original solid brick save more energy, moreenvironmentally friendly concrete hollow block to direction, and since the insulationtenon block as a new type of lightweight aggregate concrete hollow block, in thisenvironment is proposed. Since insulation block masonry composite structure is theuse of green energy-constrained bricks through a concrete frame structure in the upperand lower lateral restraint and masonry. For this the energy-saving material composedof brick masonry structure, and the use of the test article analyzes, theoreticalarguments and finite element analysis tools from basic mechanical properties, seismicforce performance were studied for the future since the insulation block puzzleconstraints body wall composite structure design and in-depth research to providereference to help promote the use of self-restraint insulation block masonry compositestructure.Based on the self-insulation tenon style concrete blocks and mortar andcompressive strength were measured, respectively, while the masonry flexuralstrength test, and the intensity level associated with the specification requirementsvalues were compared; right self-determination of the insulation tenon stylecompressive strength of masonry and proposed constitutive equation of the curvefrom holding tenon style masonry, and consistent compliance with the experimentaldata well; cross-section along the slit was measured shear strength and analysis, andthe specification of the intensity level for comparison.Based on a combination of self insulating masonry blocks constrained seismicperformance research, develop test programs and analysis of the test piece from thewall insulation block bound by masonry walls to determine the features and characteristics of the load displacement.Through a combination of self-insulation block masonry structural wall sheetconstraints experimental study in low cyclic loading from experimental phenomena,damage morphology and characteristics of the process, the mechanical properties,hysteresis curves, skeleton curves and normalized skeleton curve, energy dissipationcapacity and deformation capacity for self-restraint insulation block masonry wallcomposite structures were studied analysis and the results show that the combinationof self-insulation block masonry wall structure constraints have better ability towithstand earthquakes; and the test results presented by the shear constraintssuggested formula from insulation block masonry composite structure, in line with theexperimental data in this paper is better.In order to test the necessary research to supplement and strengthen effective tolayered shell element based on the theory, the use of wall design parameters andboundary conditions using the MARC analysis model, the numerical simulation ofcyclic loading program, and were stress and strain of cracking walls tablets wereanalyzed, the results showed that the numerical simulation and failure mode of thedestruction site in good agreement; hysteresis curve in the overall numericalsimulation under cyclic loading hysteresis curve of compliance with this test is good,and both the ultimate load error is less than3%.
