Sichkarenko S. Development and application of the approximate superelement method for calculation of the objects of complex shape.

The approximate superelement method for calculation of spatial carrier systems of buildings is developed. The scheme of an approximate superelement for the "START" program code is improved. The system of generalized forces for a superelement is derived, the algorithm of their calculus is designed. The numerical experiments affirming a high accuracy of the method, stability of computing process are conducted. In outcome the field of application of the "START" code on buildings of various systems, such as cross-wall construction, panel, monolithic, from local stuffs is expanded. The ways of the subsequent advancing of the scheme of approhimate superelements are established. The numerical researches of frameworks of buildings cross-wall construction system are conducted, which one have revealed some nontrivial features of their spatial functioning. The efficiency MASE for detection of effects of a combined working of monolithic ceiling and vertical elements of a framework is verified, including seismic effects.
