The Experimental Study On Seismic Behavior Of The QX Thermal-insulating HPC Blocks Wall

the QX thermal-insulating HPC blocks wall is made of HPC and Insulation materials. The seismic behavior of this new type of block wall material is studied in this paper.This kind of rapid wall has been widely used in the project. The foam mortar material and polystyrene board material can be used as the Insulation materials, after in the hole HPC to be possible to be used as the bearing wall. The seismic behavior of this new block wall with different height-width ratio-. mortar rating and vertical load under the lateral load is studied in the experiment. The use of this new block wall will be widely promoted since many useful datas for design are offered by the experiment. The conclusions obtained include:1.Inclined cracks of the specimen along the block itself destroyed, not along the mortar stepped diagonal crack the mortar joint, and the destruction of a brittle failure characteristics.No significant effect of the strength of the mortar masonry shear capacity.2.The aspect ratio is smaller, the greater the bearing capacity of masonry; vertical stress the greater, the greater, the carrying capacity; and the aspect ratio is greater than the vertical stress. Significant effect of the strength of the mortar masonry shear capacity.3.Specimen width than the smaller, more energy absorption, energy consumption, the better, while the strength of mortar and the vertical pressure on the energy consumption impact is not obvious.4. Aspect ratio and vertical stress affect the ductility of the specimen.the greater aspect ratio, the better ductility;The greater the vertical compressive stress, the worse ductility.Ductility factor of the specimen can be calculated as follows.λ= 5.832+2.792(h/b)-1.072σ05.The high aspect ratio increases the crack stiffness rapid decrease;while the strength of mortar and the vertical pressure on the crack stiffness is not obvious.The crack stiffness can be calculated as follows. k= 243.09-154.52(h/b)6.The stiffness of the specimen in loading the initial rate of degradation, especially before specimen cracking. Loading stage, the stiffness degradation is slow, with the displacement of the increase in stiffness of slow decay, the specimen stiffness degradation curves are relatively similar.7.Shear strength(f(?)) and lateral bearing capacity(Pu) of the QX thermal-insulating HPC blocks wall can be calculated as follows. f(?)= [0.567-0.134(h/b)]×1.16(?)(?) Pu=A·f(?)...
