Particular Features of Calculation and Design of Long-span Membrane Roofs

AbstractIn the article general approaches to design of long-span membrane roofs which are based on the use of limiting state method, and direct methods of the reliability theory are formulated. Criteria of reliability for an assessment of design solutions of structures are formulated, the general approaches to their determination are given on the basis of a probabilistic form of final element method and engineering method of reliability indicators determination. Some data are given about structural non-linearity influence on the element stability estimation of external compressed-bent contour of the membrane roofs on rectangular and elliptic plans
