Aerated Concrete Block Wall Filled Study On Seismic Perfomance Of Rc Frame Structures

A large number of earthquake damage that constructing a reasonable frame structure seismic performance is superior to the the general masonry structure and the bottom frame structure and with space layout flexibility, It has the advantages of easy-to-use, have been widely used. Aerated concrete block as a new type of wall materials gradually become the ideal of the frame structure and superstructure, the inner and outer wall, because of its light weight, high strength, and acoustic insulation, easy to process and green, etc. material. Practical engineering infill walls on the behavior of the main frame structure has a significant effect, under the premise of considering the role of infill walls of aerated concrete block infill walls of the seismic performance of RC frame structures carried out research. In this paper, large-scale software PERFORM-3D pure frame and infill walls in the plane or facade irregularly arranged six states modeling and computational analysis, based on the modal calculation results summed up aerated concrete block infill walls on the subject frame stiffness and natural period studied, summed up the the schedule calculation results based on the dynamic elastoplastic RC frame structures with aerated concrete block infill walls in the general law of the mechanical properties in the earthquake, mainly to expand the work are as follows:1、According to the large number of documents from a theoretical point of simple exposition infill walls in force after the destruction experienced several stages, the typical failure modes and included in the infill walls of the frame structure simplified calculation model, analysis modelthe advantages and disadvantages of the final Optional Polykaov recommended can reflect the infill walls in earthquake mechanical properties equivalent diagonal bracing model.2、Brief introduction to nonlinear analysis software PERFORM-3D operation principle, details of this paper material constitutive model.3、Selection of a typical four-story RC frame structure infilled masonry material aerated concrete blocks, according to the building use function empty frame and infill walls irregularly arranged in the plane or facade calculation model modalcalculated based on the modal calculation results summarizes the influence of infill walls on the body frame stiffness and cycle.4、The calculation model and the dynamic elastic-plastic time-history analysis, based on the schedule summarizes the general law of the mechanical properties of RC frame structures under seismic action with aerated concrete block infill walls.
