“…The masonry walls tend to develop ladder-shaped cracks and fail in shear when they are in a state of shear-compression combined stress [4,5,6]. When ladder-shaped cracks have developed, the walls don't lose shear strength because of the failure of horizontal mortar joints, these walls still have considerable shear strength, especially in the masonry experiments without mortar which were conducted by the relevant researchers.…”

The failure criteria and calculating methods of static and seismic shear strength of masonry under combined shear-compression action have been researched in this paper. According to the least energy consumption principle and the failure criteria of orthogonal anisotropic materials, the correlated formulae of masonry under combined shear-compression action are established. The correlated formulae are in good agreement with experimental results. On this basis, the calculation formulae of the static and seismic shear strength are established. The calculation formulae uniformly use the axial compression ratio as main variable to express. By analyzing examples, it shows that calculations by formulae given in this paper are in accordance with values of "Code for design of masonry structures" (GB 50003-2011) and "Code for seismic design of buildings" (GB 50011-2010). The methods in this paper may provide important references to engineering design as well as code revision.

“…Porto et al (2010) carried out extensive experimental research aimed at defining the in-plane cyclic behavior of walls assembled with perforated clay units, and the experimental behavior was modeled with four types of nonlinear finite element models. Kalali and Kabir (2010) established a set of analytical equations for determining the elastic properties of an equivalent homogeneous material of masonry, and the comparison indicated that the method not only provided suitable accuracy in estimation of the linear properties but also considered the nonlinear properties of walls. Vanin and Foraboschi (2012) reported the experimental and theoretical researches conducted on perforated brick masonry walls under in-plane loading, and the results indicated that brick arrangement strongly influenced the failure mode and load-bearing capacity of walls.…”

A new type of fired perforated brick with void ratio of more than 30% has been developed to improve the applicability of brick masonry structures. When the new perforated bricks are used for load-bearing walls, it will be a question whether the seismic performance of walls could satisfy the requirements under not obviously increasing the cost. This article presents an experimental study to investigate the seismic behavior and shear capacity of new-type perforated brick walls with high void ratio. For this purpose, six cross walls and three longitudinal walls with constructional columns under low reversed cyclic loading were tested, and the failure patterns, hysteretic characteristics, skeleton curves, energy dissipation capacity, ductility and reinforcement strain were observed. The test results indicate that (1) most new-type perforated brick wall specimens display shear failure, and hysteretic curves of cross walls are plump while there is some pinch phenomenon for longitudinal walls; (2) the specimens have considerable deformation and energy dissipation capacity, with displacement ductility factors of over 2.0; (3) the bearing capacity of walls increases but the ductility decreases with an increase of vertical compressive stress, and the bearing capacity and deformation all increase while considering the effect of horizontal reinforcement; and (4) the central brick wall and construction columns could resist shear force together before the peak load, while the shear force would be mainly born by construction columns at the later loading stage. Based on the test results, the constraint coefficient in current Chinese code was modified, and the calculation formula of shear capacity for cross walls was proposed. Comparison of calculated results with test data shows that the method will provide a way to predict the shear capacity of new-type fired perforated brick walls.
