Book Description
Este trabalho apresenta um estudo experimental sobre a redistribuição de momentos em vigas contínuas de concreto construídas em aduelas pré-moldadas, com juntas secas, e protendidas com cabos sintéticos externos. Para tanto foramensaiadas quatro vigas contínuas, com dois vãos iguais, sendo uma monolítica e as demais em aduelas pré-moldadas. Todas as vigas têm a mesma seção transversal tipo I, com dois vãos, altura da seção de 30 cm, largura do flange eespessura da alma igual a 30 cm e 10 cm, respectivamente. A viga monolítica tem relação 1/dp (vão/altura) igual a 18,75 e nas vigas em aduelas os valores desta relação foram entre 12,5, 18,75 e 25. As vigas são protendidas com dois cabossintéticos externos com traçado poligonal. Os cabos utilizados são feitos com fibras sintéticas de alta resistências (2700 MPa) e alto modulo de elasticidade(126000 MPa) conhecidas comercialmente como Kevlar. O objetivo deste estudo é examinar a redistribuição de momentos em vigas contínuas com sistemas construtivos diferentes e com diferentes relações 1/dp frente à utilização de cabos sintéticos. Os resultados mostram que a redistribuição de momentos em vigas em aduelas pode ser obtida a partir de uma viga monolítica semelhante e que o comportamento da redistribuição de momentos nas vigas em aduelas é pouco influenciada pela relação l/dp.

Moment Redistribution in Reinforced Concrete Beams and One-way Slabs Using 500 MPa Steel

Languages : en
Pages : 214
Book Description
In the Australian Standard, AS 3600-2001, the neutral axis parameter Ku is used as a convenient, but approximate, parameter to design for moment redistribution in building frames. The research work reported herein was conducted to obtain complete information regarding moment redistribution of beams and one-way slabs using 500 MPa steel reinforcement. A computer based iterative numerical method was developed to analyse reinforced two-span continuous concrete beams and one-way slabs. The method takes into account the material and geometrical non-linearities in the calculations. The deflected shape of the beam and one-way slab was calculated by dividing the span length into a number of rigid segments. The program also calculates the failure load and extent of moment redistribution. The analytical method was verified against the test results reported in the literature. The analytical results for load-deflection graphs and moment redistribution showed a good agreement with the test results. A parametric study was conducted using analytical method. The results of this study showed that moment redistribution depends not only on the neutral axis parameter (Ku) but also on the ratio of neutral axis parameter (Ku-/Ku+), ultimate steel strain (Đs̊u) and concrete compressive strength (fc). Keywords: Analysis, ductility, moment redistribution, neutral axis parameter, nonlinear, reinforced concrete, and steel reinforcement.
