The article discusses the calculations of some structures under various laws of deformation. Four laws are adopted: linear, nonlinear exponential, nonlinear with a falling branch, taking into account the creep of concrete, and nonlinear according to the experimental data. As a result of the calculation, the results are given for various efforts, comparative characteristics are given, and conclusions are drawn about the operation of structures and the work of materials. The following has been conducted: 1. Calculation of structures according to the 1st law of nonlinear deformation of materials - exponential law of deformation [1, 2, 3]. 2. Calculation of structures according to the 2nd law - the law of nonlinear deformation of concrete with a falling branch (according to Eurocode 2) [4, 5]. 3. Calculation of structures according to the 3rd law of nonlinear deformation of materials - the exponential law of deformation of the second type [1, 2, 3].
