【Abstract】 Based on the tests of prestressed and nonprestressed brick masonry walls and house models with peripheral beams and construction columns under cyclic lateral loading, four kinds of calculation methods for the ultimate lateral bearing capacity of nonprestressed brick walls with peripheral beams and construction columns are discussed. In order to reflect the influence of the prestressing force and get the formulas for prestressed brick walls, necessary modifications are made. Finally,simplified semi-empirical formulas of the ultimate bearing capacity for design are put forward, and the calculating results are well identical with the tests.更多还原
