AN IMPROVED ANALYTICAL CONSTITUTIVE RELATION FOR NORMAL WEIGHT HIGH-STRENGTH CONCRETE
International Journal of Modern Physics B, 2008In this paper, some available analytical models for the complete stress-strain curve for high-strength concrete (HSC) under uniaxial compression are examined and compared with experimental curves published in the literature. Based on these findings, a new analytical constitutive relation is proposed to generate the complete stress-strain curves for ...

Engineering Structures, 2013
Abstract This article discusses an analytical model that relates the transfer length and the prestressing strand draw-in immediately after transfer; the model is based on the elastic confinement hypothesis of the prestressing strand using concrete and/or confining reinforcement.

Shear Strength of Stud Connectors in Lightweight and Normal-Weight Concrete
Engineering Journal, 1971Steel-concrete composite construction using normal weight concrete has been used since early in the 1920s. Substantial use of composite construction began mainly for bridge structures in the 1950s as a result of the work done by Viest. Its primary growth in building construction during the last decade was a result of the simplified design provisions ...

Numerical fire resistance testing of lightweight concrete and normal weight concrete elements
1997This paper presents a numerical fire resistance testing of completely reinforced lightweight concrete and reinforced normal weight concrete structural members. The fire action is applied in accordance to normalized ISO-834 diagram. Thermal and mechanical properties of steel, lightweight concrete and normal weight concrete are linear for each level of ...

Determining the Static and Dynamic Properties of Hardened Normal Weight and Heavy Weight Concrete
Cement, Concrete, and Aggregates, 1986Abstract This paper describes a method for determining the material constants of normal weight and heavy weight concrete under static and dynamic loading at 7, 28, and 90 days. The tests were conducted at the University of California, Structures and Materials Laboratory, Berkeley, CA, for comparing the compressive strength, modulus of ...

Compressive behaviours of novel SCS sandwich composite walls with normal weight concrete
Thin-Walled Structures, 2019Abstract Novel steel-concrete-steel (SCS) sandwich composite walls with normal weight concrete (NWC) and J-hook connectors have been proposed for shear walls in buildings and protective walls in Arctic offshore platforms. Eight SCS sandwich walls with J-hook connectors and NWC were tested under monotonic compression.

GA-Based Optimization of Normal Weight Concrete Compressive Strength with Maranta Arundinacea
2018 IEEE 10th International Conference on Humanoid, Nanotechnology, Information Technology,Communication and Control, Environment and Management (HNICEM), 2018One of the notable innovations in the field of concrete technology is the development of chemical admixtures as an effective enhancer of concrete properties. However, it is acknowledged recently the harmful environmental and health impacts of these chemical admixtures, thus, paving the way to utilize sustainable green alternatives such as starch-based ...

Effect of kaolin waste content on the properties of normal-weight concretes
Construction and Building Materials, 2015Abstract This paper presents the mechanical, transport and drying shrinkage properties of normal-weight kaoline waste (KW) incorporated concretes. Six different concrete mixtures that have a constant water–binder ratio (w/b) of 0.40 and a binder (Portland cement + kaoline waste) content of 400 kg/m 3 were designed with various KW replacement ...
