DETERMINATION OF PARAMETERS OF CRITICAL CONDITION RECTANGULAR IN A PLAN CIRCULAR SHELLS

Abstract

Indexes which influence on stability of the reticulated and continuous circular constructions of shells of rectangular form in a plan are certain. A transition is carried out from continual to the cored system by introduction of equivalent inflexibilities and coefficient of filling in of net. Dependence of the critical loading is got from parameters which take into account material and sizes of construction. A computer modelling is conducted and the calculation of circular in a cut and rectangular in a plan of shells surfaces is executed. A value of power parameter is shown as a factor of estimation of stability for all considered pairs of continuous and reticulated models. The features of curvature of form certainly - element schemes are set. The number of semi waves is found in the direction of arc.
