Simulation and Computation of Large-Panel Buildings in PC LIRA-SAPR 2017
Panel housing construction is experiencing a rebirth. It is evident both in the growing volumes of construction, and the emergence of new space - planning andconstructive solutions in the field of large-panel housing construction. For conducting strength calculations, suitable multi-functional instruments (programcomplexes) which make it possible to take into account the features of such structures are required. That’s why in PC LIRA SAPR 2017, a special instrument forefficient simulation and computation of joints of large-panel buildings appeared. A special class of information objects - “joint of panels”, which makes it possibleto significantly simplify and automate the process of the simulation of joints of large panel buildings with subsequent triangulation and obtaining of the finiteelementcalculation scheme has been developed. New types of plate elements have appeared in the library of finite elements for simulating the horizontal joints of panels in linear and physically non-linear formulations. Non-linear effects of such joints are taken into account both in the simplified formulation with iterativerefinement of the joint rigidity and with the use of the step-by-step method which makes it possible to bring the structure to fracture, that is makes it possible tosimulate such effects as propagating destruction.
