Development of the hybrid dome and research of its behavior under load

The hybrid dome consists of a bearer frame, covered with a flexible fabric membrane. The frame comprises rigid upper beams and cable network at the bottom. Several embodiments of the dome are examined and the best one is selected. The process of prestressing of dome’s elements is considered. The analysis of reliability of exploitation of the dome is performed

Analysis of pneumatic envelopes arranged on rectangular plan

Rectangular pneumatic envelopes, made of a polymer film, are considered. The envelopes are subjected to non-uniform external loads, which consist of symmetric and inverse-symmetric parts. The functional dependence describing the envelope’s surface is given. The improved technique for obtaining geometrical parameters of envelopes is offered. It uses the differential equation of equilibrium, the method of least squares and the linearization procedure with Taylor series. The results of the work may be used for taking into account physical non-linear properties of polymer membranes, for estimation of changes of air-pressure in pneumatic cushions, for selection the most appropriate embodiment of the cushion from a set of possible variants
