Dimensionamento automático de estruturas de edifícios em concreto armado
… where the stories are grids, which lie on elastic supports, was developed. The system input datas are the geometric, topologic and load features of the structure, as well the material properties. The system lists the structure efforts and the reinforced sections of beams, slabs and columns …

Análise dos esforços em edifícios altos
… position in each story. The skeletons may have elastic supports, be under vertical and lateral loads and foundation displacements. The existence of diaphragrn slabs in each floor level is admitted. The analysis is made by the displacement method. Emphasis is given to the automatic programming …

Análise por computadores digitais de estruturas reticuladas no espaço, com elemento de secção variável
… , the prograrn allow the introduction of elastic supports, pre-stressing effects, thermal effects and displacements of the supports. This is done in order to give a complete generality to the program. As segments of the program there are subroutines designed to evaluate the reactions of …

New Approach to Connections Between Members of Adjacent Box Beam Bridges
… a three beam sub-assembly that was supported on elastic supports. The stiffness of the elastic supports was calibrated such that the state of stress in the joints and the relative displacements between adjacent box beams in the sub-assemblage matched those in the FSB. The three beam sub-assembly …

Análise aproximada de edifícios altos em microcomputadores
… structural model. Offset and bracing members, elastic supports, prescribed displacements and a random variation of the structural elements may be considered in this model. The code was developed in BASIC language. It has a powerful pre processor and a processor which deals efficientely with the …

Contribuição à análise tridimensional de estruturas de edifícios em microcomputadores
… loadings, foundation settlements, and possible elastic supports. It is assumed that the floor slabs are infinitely rigid in their own planes and with no bending stiffness. The analysis is linear elastic and the displacement method in a matrix formulation is used. Special attention is paid to the …

Determination of axial load and support stiffness of continuous beams by vibration analysis
… a continuous prismatic Bernoulli-Euler beam on elastic supports, subjected to a compressive axial load. The first model, which approximates support stiffnesses by an equivalent elastic foundation, is found to be inaccurate for wave lengths close to the support spacing. A discrete mass model is …

Geometrically Nonlinear Analysis of Axially Symmetric, Composite Pressure Domes Using the Method of Multiple Shooting
… to have general composite laminate construction, elastic supports at the edges and internal ring stiffeners. In addition, the analysis allows for the possibility of circumferential line loads at discrete locations along the dome meridian. The problem is a numerically unstable two-point boundary …

Vibrations of and sound radiation from some periodic structures under convected loadings
… beams, plates or shells on periodically spaced elastic supports which represent stiffener-skin interaction forces and moments. The available literature on the response of stiffened structures is first reviewed. A special infinite series of space harmonics is then evolved and employed to obtain …
