Creep and shrinkage of high-performance lightweight concrete
(AMER CONCRETE INST, 2004)
Two high-performance lightweight concrete (HPLC) mixtures with average compressive strengths of 68.5 and 75.4 MPa (9950 and 10,950 psi) were developed. Their air-dry unit weights were 1875 and 1905 kg/m(3) (117 and 119 ...
Updating concrete drying-shrinkage prediction models for local materials
(AMER CONCRETE INST, 2004)
This paper addresses the need to update existing concrete drying-shrinkage prediction models to reflect local materials. The experimental program was carried out using eight concrete mixtures of similar strength, manufactured ...
Comparative analysis of strut-and-tie models using Smooth Evolutionary Structural Optimization
(2013-11-01)
The strut-and-tie models are widely used in certain types of structural elements in reinforced concrete and in regions with complexity of the stress state, called regions D, where the distribution of deformations in the ...

A cost optimization-based design of precast concrete floors using genetic algorithms
(Elsevier B.V., 2012-03-01)
The integrated design optimization, not only the element optimization, is considered a strong trend. The integrated optimization involves the three major stages of an engineering design process namely conceptual design, ...

Dimensionamento de elementos estruturais em concreto leve
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2015-04-22)
The lightweight concrete for structural purposes is a material that has great potential for
application in various construction areas. Its main feature is the reduced density
compared to conventional concrete. This ...
