This is a pushover analysis for pile‐supported wharves considering the dynamic magnification factors due to torsional effects. The piles seismic design by deterministic approach is shown accounting plastic hinges and P‐delta effects in 2D/3D mathematical modeling. A real structure placed at high seismicity area is considered as case study in order to validate the model and provide reliable technical data. New bound limits of seismic demands associated with damage states and the best soil performance are identified. A stochastic approach is proposed to estimate the no‐exceedance probability of horizontal displacements of a semi‐flexible with respect to a flexible model. Results are plotted in terms of base shears, displacements, and energy. The advantage of the use of pushover analysis in terms of displacements is estimated in 18–38%. Other results as bound limits, hysteretic damping, plastic rotation are compared with previous studies.

The aim of this paper is to carry out a nonlinear static analysis using a case study of a pile-supported wharf in a new oil tankers port. The seismic activity in this area is very intense with the peak ground acceleration of 0.55 g; for this reason, it is very important to analyse the structural behaviour of the nonlinear situation. The analysis of the wharf, modelled in 3D by finite element method, serves to calculate the structure vibration periods (the structure’s first period is 1.68 s) and the capacity curve. The design of the structure follows traditional criteria by international guidelines, and its procedure is in accordance to classic theoretical methods and codes. For the selection of adequate characteristic earthquake input for the pushover analysis European and Venezuelan codes have been used. Besides being important to study the seismic influence on the body of the wharf and on critical elements, as well as and the interaction fluid-structure-soil, it is also important to analyse the consequences of structure failure and to estimate the maximum allowed displacement. The results show that the ultimate displacement is 18,81 cm. A port is an extremely strategic work, which needs to be carefully designed to avoid environmental damage and maintain human safety.

Tendo em vista a experiência de professores e pesquisadores do Brasil e do exterior no contexto da busca de novos e melhores métodos didáticos para ensino de Engenharia, constata-se que o uso de recursos multimídia interativa constitui uma abordagem promissora, com amplas possibilidades de aplicação em disciplinas de graduação. Nesse contexto, o presente trabalho trata do desenvolvimento de uma ferramenta multimídia de apoio ao ensino da flexão composta oblíqua no concreto armado, apresentando as suas funcionalidades, a estrutura do código e exemplos de aplicação. Para a construção da ferramenta, o applet “Verificação de seções quaisquer de concreto armado sob flexão composta oblíqua”, foi utilizada a linguagem de programação JavaTM e o ambiente de desenvolvimento NetBeans 5.5.1. O applet tratado neste artigo está disponível na Internet no endereço http://www.lmc.ep.usp.br/pesquisas/TecEdu/.
