In order to study the seismic behavior of shale fired heat-insulation block walls with ultra-thin mortar joint, ten specimens were designed and made considering the parameters of the existence of constructional column, vertical compressive stress, height-to-width ratio, ratio and form of openings, and tested under low-cycle reversed loading. The damage process and failure mode were analyzed and the load carrying capacity, hysteretic curve, skeleton curve, ductility, energy dissipation capacity and stiffness degradation were also studied. The test results indicate that the constructional column-ring beam is full play to the function of constraint for the masonry walls, and the design goal of fracture but not collapse can be achieved. Increasing the vertical compressive stress or reducing the height-to-width ratio, the shear capacity is enhanced, and stiffness degradation is slower. Because of the constructional column, the shear capacity and ductility are enhanced. Because of the opening, the shear capacity and energy dissipation capacity are poor. Finally, the formula for shear capacity calculation is proposed, which agrees well with the test results.

Through the experimental study on compressive property and shear strength of fired heat-insulation hollow block thin mortar joint masonry, the damage mechanism and damage characteristics were analyzed. The results show that only the high surface roughness block is suitable for thin mortar joint masonry. The stress concentration phenomenon is obvious due to the vertical seam without mortar, thus the continuous seam is formed along the vertical seam. The surface bonding strength of block is insufficient, so the strength needs to improve by adjusting production technology. The shear failure modes include single shear failure and double shear failure. The calculation formula of the compressive strength was established by introducing hole rate influence coefficient, and the calculation formula of the shear strength was established according to the shear strength test results. The calculation results show good agreement with test results. According to the constitutive model of reference, the calculation formulas of the stress-strain relationship and the elastic modulus are put forward. Finally the suggested value for the Poisson's ratio is 0.3.

The shale fired heat-insulation block masonry wall is a type of new energy-saving and environment-friendly building wall . Shaking table tests were conducted, considering the following three factors: the vertical spacing of the horizontal tension belt, the connection mode of infill wall and frame beam; the connection way between infill wall and frame column. Four pieces of full scale shale fired heat-insulation block masonry infill wall with four different kinds of connection ways were designed using the orthogonal experimental method to study the out-of-plane anti-seismic performance of the wall. Results show that the walls with four different kinds of connection ways can meet the requirements of "no damage under frequent earthquake, repairable damage under basic earthquake and no collapse under rare earthquake", and the wall's anti-seismic behavior of the out-of-plane are affected meaningfully by the vertical spacing of the horizontal tension belt and the connection mode between the top of the wall filled with frame beam, the connection mode between the wall filled with frame column affects lightly. In order to meet the requirement of the structural deformation in the plane, flexible connection wall with reliable steel tie bars in the top of the wall and horizontal tensile belt arranged reasonably should be adopted in the actual construction.

Shale sintered composite external wall thermal insulation brick (WDF) is a new type of exterior wall thermal insulation material. In this paper, a seismic station out of plane vibration performance test was carried out by designing a total of four pieces of RC shear wall plug WDF specimens as the full-scale mode. The effects of anchor bolt arrangement number and arrangement of components on the seismic performance of out-of-plane were mainly studied. The results of the test show that, four pieces of wall are of good seismic performance. The relative displacement between the WDF and the primary wall reaches a maximum at the top of the wall. Moreover, the anchor has an inhibiting effect on the vibration frequency attenuation of component. The effects of anchor bolt on the acceleration of out-of-plane is smaller when a number of 4 per square meter is arranged, and the relative displacement between the WDF and the primary wall is minimum. In addition, the cracks between the WDF and the primary wall are fewer and dehiscence slowly when the clubs layout form is applied, so the anti-seismic performance out-of-plane is better. Therefore, it is suggested that the clubs layout form be applied as far as possible to the actual construction.

Out-of-plane shaking table experiments on a model structure consisting of 4 full scale frame infilled walls with shale fired heat-insulation block were carried out and its response characteristics were investigated under the simulative earthquakes of El-Centro wave, Taft wave, Tianjing wave and Double El-Centro wave. The influences of the construction measures between the filling wall and frame structure on the out-of-plane seismic responses of the model structure, such as the frequency, acceleration, relative displacement and rebar strain response, were analysed. The results show that the frequency of the specimen with a wall-beam or wall-column rigid connection is reduced more slowly than that with a flexible connection, meanwhile the acceleration amplification coefficient and relative displacement become smaller, and using two binding belts can obviously reduce the out-of-plane seismic response of the model structure. By using the synthetic weighted mark method, the most influential factor on the out-of-plane seismic response of the frame infilled walls, is the number of binding belts, the type of wall-beam connection succeeds and then is the wall-column connection. ©, 2015, Chinese Vibration Engineering Society.
