Praca prezentuje analizę drewnianych elementów dwuteowych powstałych przez łączenie gwoździami. Ustalono maksymalną siłę ściskającą słup, zginającą belkę oraz ugięcie belki. Porównano wartości uzyskane przez obliczenia analityczne oraz model metody elementów skończonych (MES). Materiał traktowano jako sprężysty z izotropową oraz ortotropową strukturą.
In the article results of influence of seismic load on deformations of constructions of high-rise building with different number of floors are presented. Calculations have been made by the finite element method under direct time integration with Newmark’s scheme, taking into account damping. It is shown that maximum building oscillations can appear under partial height of a building. This effect should...
W pracy przedstawiono porównanie wyników obliczeń analitycznych oraz numerycznych przebiegu drgań prostej konstrukcji prętowej. Do obliczeń numerycznych wykorzystano program Autodesk Robot Structural Analysis.
W artykule przedstawiono analizę porównawczą przemieszczeń i naprężeń obliczonych przy użyciu programów opartych na metodzie elementów skończonych: ADINA oraz Autodesk ROBOT Structural Analysis. Do obliczeń numerycznych przyjęto jednostronnie utwierdzoną belkę stalową o skrzynkowym przekroju poprzecznym (kształtownik zamknięty prostokątny wg PN-EN 10210-2:2000) z zaokrąglonymi krawędziami zewnętrznymi...
This article describes the role of the finite element method (FEM) in the study of span structures. The choice of software for the FEM implementation has been rationalized. The use of the modern package of finite element analysis Femap with NX Nastran in order to model and calculate reinforced concrete bridge span structures has been reviewed. The sequence for reinforced concrete analysis has been...
Linear, nonlinear and test comparison analyses of flat plate slabs with shear reinforcement are presented in the article. Analyses of slabs with and without shear reinforcement by nonlinear simulations are introduced. The calculations of slabs without and with 0.16 m eccentricities were performed. For analyses finite element method were used. Design models of flat slab with column by “Lira SAPR” software...
The paper presents a reliability analysis approach of curved on plane hoist beam using the coupling of two programs: Ansys and Matlab. The analysis takes into account warping and geometrically nonlinear approach to determine the deformation of the structure. Two approaches of building a reliability function are presented: the first is based on probabilistic-deterministic design conditions and the...
The paper presents the results of punching shear values with reinforcement based on calculations of two and four storey cast–in–place reinforced concrete flat plate system buildings with spans of 4 and 7 m in accordance with Armenian, Russian, European and American building codes under seismic action. The effect of punching shear on both interior and edge columns was carried out. All calculations...
The paper presents a numerical analysis of the propagation of a disturbance in the form of a mechanical wave caused by a concentrated force applied perpendicular to the plane of the wall fragment analyzed in the work. Numerical tests were carried out on a numerical model of concrete blocks with rubber filling and on hollow concrete blocks, as a reference model. The impact of using concrete-rubber...
The problem of analysing complex steel structures in relation to analytical and numerical tests of a single structure element has been presented. The aim was t o demonstrate the compliance of the chosen methods for determining the strength parameters of a cantilever beam and to select the best cross-section for the optimization of the structure. The beam deflection and the value of the maximum reduced...
In this study, the non-preloaded bolted connection of a roof girder, commonly used in steel halls with a frame system, was analyzed. Two options were considered: a connection before reinforcement and one reinforced by adding a new row of bolts. For both of the analyzed variants, analytical calculations were performed based on the component method and numerical calculations using the Finite Element...
