Avaliação experimental por meio de ensaios cíclicos de pórtico de aço preenchido com alvenaria participante
… experimentais, numéricos e analíticos têm sido desenvolvidos a respeito de estruturas compostas por pórticos preenchidos com painéis de alvenaria. Apesar de já ser comprovado o aumento de rigidez proporcionado por estes painéis, os mesmos quase sempre são tratados apenas como material de vedação …

Análise de placas circulares sobre base elástica
The subgrade reaction method and that of the rigidity modulus were applied in order to calculate the model foundation plate, built in acrilic and supported on a sandy foundation very carefully mounted. Comparing the theoretical resulta with the ones experimentally reached, we can define, in this …

Estudo de deformação vertical de pavimento para o dimensionamento de recapeamentos
A new feature concerning design of overlays for flexible pavements is presented. The development is based on the expression of surface deflection according to the theory of elasticity for a two-layered system, and with due consideration of empirical correlation between traffic characteristics and …

Lajes de pontes pelo método da ruptura
… refers to the application of rupture method on designing of bridge slabs. We have studied only the effect of the heavy vehicle of six wheels. We have tested 5 models, being 3 separeted and just supported by the 4 sides, and 2 continuous slabs that have been previously dimensioned, according to …

Dimensionamento automático de estruturas de edifícios em concreto armado
The design of reinforced concrete multistory building by computer is the goal of this work. A FORTRAN IV language system, 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 …

Um sistema automático de projeto de estruturas ótimas
… automatic sizing of large-scale structures is developed, making use of an "optimali ty cri terion" algori thm, where inequali ty constraints are treated with the aid of slack-variables. Attention is focused on fixed geometry structures which can be idealized using finite elements. Multiple …

Estudo de flexão composta oblíqua em seções retangulares simétricas
A computer program was developed in order to design reinforced retangular full or hollow concrete sections with symetrical uniformly distributed reinforcement under biaxial bending. Theoretical bases followed CEB-FIP-1970 recommendations. Comments on grafical methods for design and checking were …
