Straight Joint Shear Performance Test of Urban Sludge Sintered Shale Bricks

In the actual engineering design, it is too conservative for the calculation results for the urban sludge sintered shale brick to use the shear strength formula in the Design Specifications of Masonry Structure. To more effectively calculate this formula, this paper researches the straight joint shear performance test of urban sludge sintered solid shale bricks and porous brick masonry, and analyzes the failure mode of two kinds of brick masonry, and reaches the proposed formula of the straight joint shear strength. Then, this paper compares the proposed formula with the corresponding formulas in the specification, and reaches a high safety stock of the formula in the specification, and needs to correct the coefficient of material properties in the formula in the specification.
