The Concrete Damage Plasticity (CDP) model is a widely used constitutive model to represent the non-linear behavior of concrete in numerical analysis. However, a limited number of studies compared the level of accuracy of numerical models with the ma

ABSTRACT: Provided that the anchorage capacity is guaranteed at the supports, the bearing capacity of hollow core slabs depends on the shear capacity of the pretensioned concrete webs, wherein the critical section is in a region between h and 2h from

RESUMO Diferentemente das estruturas moldadas no local, os sistemas pré-moldados de concreto apresentam basicamente como particularidades: projeto das ligações e a consideração de outras situações de cálculo diferentes da final de projeto. Es

As estruturas pre-moldadas de concreto sao, convencionalmente no Brasil, sistemas de porticos nao contraventados com pilares continuos. Sendo os pilares responsaveis pelo fornecimento de estabilidade lateral e transporte dos carregamentos verticais.

In this paper, a nonlinear finite element analysis of slab-beam-column connection in precast concrete structures is presented. The detailed experimental results of the full-scale connection have been discussed in a different paper. However, due to th

This paper provides an experimental investigation on the moment-rotation response of typical moment resisting beam-column connections, employing continuous negative bars consolidated with cast in place concrete over the precast beam and passing throu

Precast structures for multi-storey buildings can be designed with economy, safety and high performance. However, depending on the height of the building and the intensity of the lateral loads, the lateral stability system must be carefully chosen in
