The Four-storey Building Waste As Recycled Brick Masonry Structure Shaking Table Test

in order to study the aseismatic performance of the construction waste brick, the performance of the model for the tests, the four layers of construction waste recvcled brick model and the aseismaiic performance of building the system research, and to the seismic design of brick masonry structure thoroughly discussed. For related national technical standards to provide the basis. This paper main research work are as follows:First of four construction waste brick building structure model regeneration simulated seismic shaking table test, the geometric similar model than take1:3to EL-Centrc wave. Taft wave and artificial seismic wave of input, the magnitude of the different intensity test, and observed the cracks of the test of development and failure mechanism. Examine the experimental stage in each model of seismic response. deformation condition and characteristics of earthquake damage. In the simulated seismic before the test and simulation test each stage after the earthquake are on the model white noise scanning experiments, examines the change law of the frequency of the model. Analyzes the mechanism of earthquake damage, the seismic performance and overall seismic capability is evaluated. Experiment shows that the model has better seismic performance, according to the requirements of seismic code design the four layers of construction waste recycled brick masonry structure suffered from8degrees earthquake, can realize the "small earthquakes are not bad. but the shock of the earthquake, not" goal.Second is theoretically proved the frequency of masonry structure with the law of the stiffness, the conclusion and shaking table test results are in agreement. This for the next press stiffness loss science evaluation structure provides a theoretical basis for earthquake damage, found a new effective way.
