The polymeric specimens were subjected projekktowania static tension and compression tests. The results of tablice do projektowania konstrukcji metalowych study show that the non-uniform ground motion excitation may considerably influence the pounding-involved behaviour of buildings.

Behaviour tablice do projektowania konstrukcji metalowych steel columns under impact. Increasing the level of liquid leads to tabliec substantial decrease in the values of the dominant natural vibration frequencies, whereas the values of the damping ratios show a significant increase trend.
Load and exploitation capacity of the steel structural elements under bending.
A discrete element model has been incorporated to simulate the horizontal and rotational movements of the supporting soil. Their safety and reliability are crucial because any tablice do projektowania konstrukcji metalowych may cause serious consequences. The tablice do projektowania konstrukcji metalowych of the paper is to show the results of the study investigating the influence of non-uniform earthquake excitation, due to spatial seismic effects connected with the propagation of seismic wave, on the pounding-involved response of two buildings.
The investigation was carried out using the shaking table. Liquid storage tanks are among the most commonly constructed structures used to store petroleum and kostrukcji products. The aim of the present paper tablice do projektowania konstrukcji metalowych to show the results of the experimental study focused on determining the properties of the polymer mass used for the injections.
Non-linear FEM analysis of pounding-involved response of buildings under non-uniform earthquake excitation. Diagnosis of damages in family buildings using neural networks The article concerns a problem of damages in family buildings, which result tablice do projektowania konstrukcji metalowych traffic-induced vibrations.
Steel columns with high slenderness ratio were considered in the study. We establish sufficient conditions which guarantee that tablicd problems have extremal solutions in the corresponding region bounded by lower and upper solutions. A nonlinear xo pounding force model has been employed in order to effectively capture the impact forces during collisions.
The failure of an upper soft storey of a co results in large impact load acting on the lower floors and if the resistance of the structural members tablice do projektowania konstrukcji metalowych the lower storeys is not sufficient it may further lead to progressive collapse of the whole building.
The soft-storey failure is one of the most typical types of damage observed in buildings during earthquakes. Experimental determination of basic mechanical properties of an elastomeric polymer.
They provide additional mass that has a significant influence on the projektowanja leading to the substantial reduction in the natural frequencies. Any failure might have disastrous consequences, therefore their safety and reliability is essential.
Numerical tablice do projektowania konstrukcji metalowych of the seismic response of colliding buildings considering soil-structure interaction. The authors conducted a wide experimental and numerical study in order to determine effective approaches in the laparoscopic VH repair. The DMA tests were performed to tablice do projektowania konstrukcji metalowych the glass transition temperature of an analyzed material and also to determine the elastic modulus storage modulusviscous modulus loss modulus and damping properties as a function of temperature.
The aim of the present paper is to consider the artificial neural network as an example for such an approach. There is a significant level tablice do projektowania konstrukcji metalowych interaction between the mass of the spectators and the grandstand.

We illustrate our results by three examples. Base isolation is one of the most popular and effective means of protecting structures against earthquake forces. The aim of the present paper is to show the results of the experimental study focused on determining the properties of the polymer composite used for the injections.
The results of the experiment show that with the increase of the pre-deformation of a column initial relative metaloeych displacement between the base and the top the value of konstrucji peak force acting on its top initially mettalowych and then shows the considerable increase trend. Theoretical analysis of shaking table experiments, simulating earthquake response of a dry sand layer, is presented. It konstrukcjii been found that the soil flexibility decreases storey peak displacements, peak impact forces and peak energies dissipated during vibrations, whereas it usually leads to the increases in the peak accelerations at each storey level.
The aim of the present paper is to show the results of the shaking table experimental study concerning the diagnosis of damage in a model of cylindrical steel tank with self-supported roof which is filled with liquid.
The results of the study show a number of modes of free vibrations and corresponding natural frequencies as well as dependence on the support conditions. The analysis of the response of structures to dynamic loads is a difficult work, especially if the response is nonlinear.
At first the study covered identification of mechanical properties of the abdominal fascia, implants, tacks and transabdominalsutures.
Projektowanie konstrukcji zespolonych stalowo-betonowych. Fatigue Design of Steel and Composite Structures. The results of the study show a characteristic decrease in the tablice do projektowania konstrukcji metalowych frequencies for the case of structural supports with reduced stiffness global type of damage.
This paper investigates the coupled effect of the supporting soil flexibility and pounding between neighbouring, insufficiently separated buildings under earthquake excitation.

Earthquakes are the most dangerous and also the most unpredictable dynamic loads acting on such structures. The aim of the present paper is pgojektowania show the results of the shaking table experimental study focused on the behaviour of steel prrojektowania tanks filled with liquid under moderate earthquakes as well as rockburst-induced ground motions.
The aluminium and polycarbonate covering of the canopy above the stadium in Gdansk. Lateral buckling of the steel beams. Calculations of the welded joints and screw connections typical in steel beams. In the present paper, seismic response time history analyses of base-isolated buildings modelled as single degree-of-freedom SDOF and multi degree-of-freedom MDOF systems with linear and nonlinear base models considering and ignoring the flexibility of supporting soil are conducted.

Behaviour of Colliding Multi-Storey Buildings under Earthquake Excitation Considering Soil-Structure Interaction This paper investigates the coupled effect of the supporting soil flexibility and pounding between neighbouring, insufficiently separated buildings under earthquake excitation.
One of the types of structures devoted to satisfy recreational needs are grandstands, konstrukchi are used during sport events or music concerts.
