  abstract  = {Seismic insulation is one of the most progressive types of seismic protection. Seismic insulation is understood as applying special devices for reducing of inertial seismic loads acting on a building. The constructions, shown in article, significantly more effectively solve problems of seismic protection, comparing to the existing seismic insulation systems (SIS). The Special Mechanical Engineering Design Office has developed, manufactured and tested a shock-absorber unit (SAU) of large load capacity. The SAU represents a block of number of pneumatic shock-absorbers (PSA), concentrically mounted round the guiding cylinder. The protected object rests upon the upper movable part of the guiding cylinder of the SAU. In its turn, the lower part of the SAU is rested on the foundation plate, mounted on the ground. A set of the SAU is a constructive realization of the SIS. Efficiency of such SIS has been proved as theoretically, so experimentally An effective SIS can also be created on the base of the elasto-plastic shock-absorbers developed by the KBSM. New designing and constructional solutions are based on the use of the original SIS elements, performed on the base of long time existing (in the other field of technical equipment)units, safety and durability of which have been proved by long term service (more than 20 years).},

  abstract  = {One of the basic types of strength calculations is the calculation of limit equilibrium of constructions. This report describes new method for solving the problem of limit equilibrium. The rigid-plastic system in this method is substituted with an «equivalent» elastic system with specially constructed rigidities. This is why it is called the method of pseudorigidities. An iteration algorithm was developed for finding pseudorigidities. This algorithm is realized in a special software procedure. Conjunction of this procedure with any elastic calculation program (base program) creates a program solving rigid-plastic problems. It is proved, that iterations will be converge to the solution for the problem of limit equilibrium. The solution of tests show, that pseudorigidity method is universal. It allows the following: - to solve problems of limit equilibrium for various models (arch, beam, frame, plate, beam-wall, shell, solid); - to take into account both linearized and square-law fluidity conditions; - to solve problems for various kinds of loads (concentrated, distributed, given by a generalized vector); - to take into account the existing various of fluidity criteria in different sections etc. The iterative PRM process quickly converges. The accuracy of PRM is very high even in case of rough finite-element structuring. The author has used this method for design protection systems from extreme loads due to equipment of nuclear power stations, pipelines, cargo in any transportation.},
