In Brazil, the use of reinforced concrete waffle slab in multi-story buildings is widespread nowadays. These buildings are projected for different purposes such as fitness centers, supermarkets, parking garages, offices and residential units. Simple activities as walking, skippin...

Waffle slabs are, nowadays, a demand for structural designers, as a consequence of architectural design evolution and new building management concepts, in spite of its laborious numerical modeling. Therefore, it becomes necessary to know more about their structural behavior and t...

This work has as main objective to contribute for the development of a methodology capable to determine through numerical simulations the displacements in waffles slabs, submitted to uniformly distributed loading. It was analyzed a unidirectional waffle slab and another bidirecti...

Two-way waffle flat slabs are structural elements of reinforced concrete supported directly on columns, under bending moments over the two directions, they improve the speed of the execution and save moulds and concrete and, consequently, labor. This work seeks to contribute for ...

Concrete flat slabs prestressed with unbounded greased strands have been used in building floors over the last years. This structural solution is ideal when the columns are regularly distributed. In addition, it is known that prestressed floors have some technical advantages when...

Resumo Este trabalho de investigação científica aborda a análise da rigidez tangente à torção de lajes nervuradas de concreto armado por meio de comparações da análise numérica com resultados de ensaios experimentais, cujo cálculo foi feito no programa ATENA. Tal programa foi des...

Lajes nervuradas modeladas computacionalmente são geralmente analisadas por metodologias simplificadas, tanto para a geometria da seção (convertendo em lajes maciças ou grelhas) como para as propriedades mecânicas dos materiais (regime elástico-linear). Estes estudos teóricos apr...
