Local Destruction

At present, the current legislative and regulatory documents do not contain a clear and unambiguous answer to the question, what buildings and structures should be designed resistant to progressive collapse. In this regard, the analysis of the legal and regulatory requirements of the need for calculations to prevent the progressive collapse of buildings and structures due to hypothetical or suspected local destruction is presented. The main legislative requirements of technical regulation in the field of ensuring the mechanical safety of buildings and structures, as well as the requirements of regulatory documents regarding the design of the protection of building and structures against progressive collapse are considered. The analysis of the fundamental principles features of the calculation for the structural protection against progressive collapse is given. Some issues discussed by the professional community in the direction of possible ways of solving the actual problems of the presented problem are considered. The conclusion is made about the need for further dialogue of the professional community on the development of a common position on the protection of buildings and structures from progressive collapse, which should be reflected in the legislative and regulatory requirements.

Hinged Support

Geometric nonlinearity shallow shells on a square and rectangular plan with constant and variable thickness are considered. Loss of stability of a structure due to a decrease in the rigidity of one of the support (transition from fixed support to hinged support) is considered. The Bubnov-Galerkin method is used to solve differential equations of shallow geometrically nonlinear shells. The Vlasov's beam functions are used for approximating. The use of dimensionless quantities makes it possible to repeat the calculations and obtain similar dependences. The graphs are given that make it possible to assess the reduction in the critical load in the shell at each stage of reducing the rigidity of the support and to predict the further behavior of the structure. Regularities of changes in internal forces for various types of structure support are shown. Conclusions are made about the necessary design solutions to prevent the progressive collapse of the shell due to a decrease in the rigidity of one of the supports.
