  abstract  = {Rectangular steel frames are considered and subjected to strong ground motion. Their behavior factor is numerically evaluated using nonlinear time history analysis and different ground acceleration records. The behavior factor is determined assuming severe collapse mechanism occurs throughout the time history. The system of equations is transformed into single equation end then the energy balance concept is applied. The expression for the behavior factor is derived and its application to four story two bays steel frame is illustrated and the corresponding results are discussed.},

  abstract  = {The steel structure design codes require to check up the member strength when evaluating plastic deformations. The model of perfectly plastic material is accepted. The strength criteria for simple cross-sections (I section, etc.) of steel members are given in design codes. The analytical strength criteria for steel cross-sections and numerical approaches based on stepwise procedure are investigated in many articles. Another way for checking the carrying capacity of cross-sections is the use of methods that are applied for defining strain-deformed state of elastic perfectly plastic systems. In this paper non-iterative methods are suggested for checking strength of cross-sections. Carrying capacity of cross section is verified according to extremum principle of plastic fail under monotonically loading and the strain-deformed state of cross-section is defined according to extremum energy principals of elastic potential of residual stresses and complementary work of residual displacements. The mathematical expressions of these principals for discrete cross-section are formulated as problems of convex mathematical programming. The cross-section of steel member using finite element method is divided into free form plane elements. The constant distribution of stresses along the finite element is accepted. The relationships of finite elements for static formulation of the problem are formed so, that kinematics formulation relationships could be obtained in a formal way using the theory of duality. Numerical examples of determination of cross-section strength, composition of interactive curves and composition of moment-curvature curves for different axial force levels are presented.},

  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  = {There was suggested a phenomenological modified quadratic condition of the beginning of plasticity for plastic and quasifragile orthotropic materials. Limiting surface in the shape of a paraboloid with an axis bend over hydrostatic axis corresponds to the condition. The equations of theory of current with the isotropic and anisotropic hardenings, associated with the suggested yield condition, modified into the version of determining equations of strain theory of plasticity are received. These defining equations formed the basis of highlyprecise non-classic continual (along thickness) theory of non-linear deformation of thick sandwich plates and sloping shells. In the approximations along the cross coordinate the specificity of flexural and non-flexural deformations is taken into account. The necessity of introducing the approximations of higher order, as well as accounting for the cross compression while decreasing of the relatively cross normal and shear layer rigidness is shown. The specifications, obtained in comparison with the known physically nonlinear specified model of the bending of plates with orthotropic layers are distinguished. An effective procedure of linearization of the solving equations and getting the solutions in frames of the discrete-continual scheme of the finite-element method is suggested. The approximations of higher order let to model the appearance of the cracs of layers being split by the introducing of slightly hard thin layers into the finite element, not violating the idea of continuality of theory. Calculation of a threelayer plate with rigid face diaphragms on the contour is considered},

  abstract  = {In many engineering applications two or more different interacting systems require the numer-ical solution of so-called multifield problems. In civil engineering the interaction of fluid and structures plays an important role, i.e. for fabric tensile structures of light and flexible materials often used for large roof systems, capacious umbrellas or canopies. Whereas powerful numerical simulation techniques have been established in structural engineering as well as in fluid mechan-ics, only relatively few approaches to simulate the interaction of fluids with civil engineering constructions have been presented. To determine the wind loads on complex structures, it is still state-of-the-art to apply semi-empirical, strongly simplifying methods or to perform expensive ex-periments in wind tunnels. In this paper an approach of a coupled fluid-structure simulation will be presented for membrane and thin shell structures. The interaction is described by the struc-tural deformation as response to wind forces, resulting in a modification of the fluid flow domain. Besides a realistic determination of the wind loads, information on the structural stability can be obtained. The so-called partitioned solution is based on an iterative frame algorithm, integrating different codes for Computational Fluid Dynamics (CFD) and for Computational Structural Dy-namics (CSD) in an explicit or an implicit time-stepping procedure. All data exchange between the two different applications is performed via a neutral geometric model provided by a coupling interface. A conservative interpolation method is used for the interpolation of the nodal loads. The time-dependent motion of the structure requires a dynamic modification of the different grids and a redefinition of the Navier-Stokes equations in an Arbitrary Langrangian Eulerian (ALE) formulation. As an example for the present implementation, results of a coupled fluid-structure simulation for a textile membrane canopy will be presented.},

  abstract  = {A fuzzy logic controller - WNC (Water Network Control) was developed for control of urban drainage systems. The objectives are to avoid accidents, flooding, pollutions through combined sewer overflows and excessive operation and maintenance costs. Fuzzy logic was proved to be a promising approach, flexible and easy accepted, because it includes the expert knowledge. Fuzzy control system proposed is robust and also easy to understand and modified. It offers to the operator the possibility to participate directly in the system control, combining the results of the modern optimization techniques with the experience and knowledge accumulated in time by experts. Thus, the control of urban sewer system can be well solved by implementing an intelligent control system, based on available information (fuzzy) and on expert's experience. An important feature of this fuzzy logic system is its capability to elaborate a control decision even in situations that were not considered in the design phase of the urban network.},
