Determinação da rigidez à rotação de ligações pré-moldadas utilizando o método dos componentes

Abstract

Considering the increasing demand for workers in construction, along with the rising cost of skilled labor, building systems that aim to gain in productivity is conquering space. This gain occurs through processes that reduce the runtime of the structure, the number of employees at the work site, and its size. Within the choice of the structural system, the most common solutions in these situations are the steel structures and buildings in precast concrete, which demonstrate a much more mechanized and industrial face to the construction environment. Systems, such as steel and concrete precast have a basic difference in relation to conventional concrete structures, which is the connection. The structure, different from the more usual processes, is assembled from parts, which are in general, pillars, beams and slabs. This work aims to develop a methodology and a program to determine the stiffness of these connections in structures of precast concrete systems conventional or not. For it, will be used the components method validated by experimental results in the literature.
