A new reinforcement measure with no-fire operation is presented, which is very suitable for space trusses which are located in gas stations. A finite element model (FEM) is presented with shell elements and multipoint constraint elements. With this FEM, nonlinear analyses are carried out. Analytical results show that integral failure of reinforced pipe is caused by yielding of original pipe inside. So it is not necessary to reinforce original pipe using steel pipe bonded outside with high yield strength. With the increase of length of bonded pipe outside, loading according to elastic stage and ultimate bearing loading increase, it is clear that the length of bonded pipe outside is an important factor which influences the bearing capacity.

Loss Factors

Since double layer space trusses have typically a large number of redundant members, it is frequently assumed that they are quite safe as the loss of one or more members can be accommodated without any noticeable effect on truss overall behaviour. The present study shows that every truss includes a number of critical members, the loss of any of which would cause force distributions that could lead to an overall premature collapse. The sensitivity of space trusses to member loss is clearly identified. The composite action between a top concrete slab and a space truss is also introduced as a means to control truss sensitivity to member loss. Factors that affect this sensitivity such as the truss supporting conditions are also investigated.

Space Trusses

Uma das aplicações interessantes da engenharia civil é a treliça espacial, um elemento tridimensional, particularmente utilizado como cobertura para estruturas industriais e comerciais, cobrindo grandes áreas abertas com poucos ou nenhum apoio interno. Este artigo tem como objetivo comparar diferentes métodos numéricos implementados computacionalmente para a solução do sistema de equações lineares gerado da iteração de Newton-Raphson no processo incremental. A solução numérica de tais sistemas lineares écomputacionalmente onerosa, portanto é do nosso interesse determinar quais métodos numéricos melhor se adéquam ao problema. Para comparar o custo computacional dos algoritmos, um estudo da complexidade é realizado. Simulações numéricas com o programa Matlab são feitas de problemas de treliças espaciais com comportamento não linear geométrico. O sistema de equações não lineares é solucionado com o método de Newton-Raphson Padrão associado a técnica de continuação Comprimento de Arco Linear. As estruturassão discretizadas por meio do método dos Elementos Finitos Posicional, cujas variáveis fundamentais são as posições nodais do elemento finito. Para o tempo de processamento, os resultados numéricos indicam um melhor desempenho dos métodos iterativos em comparação com métodos diretos, especialmente para problemas de ordem maior, que são comumente os mais encontrados na área estrutural.
