THE STRENGTH AND DEFORMABILITY OF PRECAST-MONOLITHIC PLATFORM JOINTS OF PANEL BUILDINGS

Abstract

Given a new constructive solution of precast-monolithic platform butt joint panel stand-frame and the disk overlap panel buildings, Otley significant feature of which is the presence of a special centering device to improve the accuracy of installation of the panels-frames. Given the estimated model of the design of the junction and the analysis of the stress-deformirovannogo status of this design at various levels of loading with nonlinear deformarea-tion and cracking. A special method of "jointing" of plane-stressed finite elements along the boundaries of these elements was used to model cracks. The analysis of deformation, crack formation and destruction of the considered structure of the platform joint is carried out. It is shown that the proposed version of the computational model with the task of explicit cracks-cracks "jointing" allows to predict the scheme of the platform joint development.
