Analysis of Masonry Panels using the No-Tension Approach

摘要

A computational procedure for two-dimensional equilibrium problems, which are representative of the behaviour of masonry walls loaded by in-plane forces, is analysed in the paper. The solution is searched through a procedure according to the conjugate gradient method interpolated with relaxation intermediate steps. The procedure is tested from the point of view of accuracy and convergence, with reference to a masonry wall with openings, stringcourses and architraves, subject to a horizontal force. Finally some laboratory experiments concerning the lateral loading of a door-panel are reported, and the comparison with the numerical results relevant to a FEM no-tension model of the specimen is discussed.
