The Finite Element Analysis

Abstract To study the influence of soil-well bore-shaft tower interaction on the seismic response of the shaft tower. A numerical analysis model of rigid foundation (without considering the interaction of soil-well bore-shaft tower ) and II site considering soil-well bore-shaft tower interaction is established by the finite element analysis method. The mode period, tower layer displacement and inter-story displacement of shaft tower are analyzed. The results show that, compared with rigid foundation, considering the interaction of soil-well bore-shaft tower, the mode period of the system is prolonged, the tower layer displacement and inter-story displacement of the shaft tower is enlarged. In the engineering design of shaft tower, the influence of the soil-well bore-shaft tower interaction on the seismic response of the shaft tower cannot be ignored.

Abstract A finite element formulation to solve the dynamic behavior of high-speed Shinkansen cars, rail, and bridge is given. A mechanical model to express the interaction between wheel and rail is described, in which the impact of the rail on the flange of wheel is also considered. The bridge is modeled by using various finite elements such as shell, beam, solid, spring, and mass. The equations of motions of bridge and Shinkansen cars are solved under the constitutive and constraint equations to express the interaction between rail and wheel. Numerical method based on a modal transformation to get the dynamic response effectively is discussed. A finite element program for the dynamic response analysis of Shinkansen cars, rail, and bridge at the high-speed running has been developed. Numerical examples are also demonstrated.

The results of theoretical research and earthquake damage investigation show that seismic response analysis of different plane structure in horizontal direction is different. Dynamic characteristics and seismic response analysis of four kinds of architectural models with different planes were analyzed by using the finite element analysis software. The inherent characteristics and earthquake time-history curves in different intensity level X, Y direction of displacement, velocity, acceleration and angle displace were studied. The results show that the seismic response of the four kinds of structures separates gradually, and the separation gap increases with increase of earthquake intensity. The building structure is safer in the long side direction than that in the short side in lateral earthquake response. The irregular structure can cause strong response in both horizontal in a single direction of earthquake effect. The second floor is a weak layer of the building structure which should be paid more attention to.

Hydrodynamic Coupling

Floating roofs are widely used to prevent evaporation of contents of large cylindrical oil storage tanks. The 2003 Tokachi-Oki earthquake caused severe damage to floating roofs due to liquid sloshing. Seven single-deck floating roofs deformed to leak oil on them, and they lost buoyancy to sink. Two of them were the single-deck type with center pontoon in large diameter tanks. The present paper deals with an axisymmetric finite element analysis for the sloshing response of a floating roof with center pontoon. The hydrodynamic coupling of the fluid and the floating roof under seismic excitation is taken into consideration in the analysis. The fluid is assumed to be incompressible and inviscid, and the roof is assumed to be linear elastic. In addition, the sidewall and the bottom are assumed to be rigid. In the finite element analysis, the behavior of the fluid is formulated in terms of dynamic pressure using the Eulerian approach. The basic vibration characteristics of the single-deck floating roof with center pontoon, such as the natural periods and vibration modes, can be obtained from this analysis. These characteristics are shown comparing with those of the single-deck floating roof without center pontoon. The seismic response analysis for the input of an earthquake wave is also performed.

The Impact

Abstract In this paper, an evaluation was tried for the impact of structural design on structural response. Several situations are foreseen as the possibilities of changing the distribution of the structural elements (sails, columns, etc.), the width of the structure and the number of floors indicates the adapted type of bracing for a given structure by referring only to its Geometric dimensions. This was done by studying the effect of the technical design of the building on the natural frequency of the structure with the study of the influence of the distribution of the structural elements on the seismic response of the building, taking into account of the requirements of the Moroccan earthquake regulations 2000/2011 and using the ANSYS APDL and Robot Structural Analysis software.
