MULTIFUNCTIONAL BEARING MEMBER OF BUILDINGS AND STRUCTURES

摘要

general and special mechanical engineering; civil and industrial construction engineering. SUBSTANCE: multifunctional bearing member has metal center plate placed in case and enveloped by side metal plates supported by flexible cases taking inner pressure built up by external pressure source. Some active mechanisms of resistance are introduced and installed in longitudinal surface of center plate at points of expected elongation and compression of center plate when it takes external thrusts; active mechanisms of resistance are made in the form of multiple section piston set with rod installed in case accommodating working medium; case interiors communicate with external pressure sources through distributing pipelines and manifold; pistons or rod proper and each section of case are joined to metal plates. EFFECT: enhanced bearing capacity at increased outer static or transient load. 2 cl, 5 dwg
