Adiabatic temperature rise (ATR), early-age strength development for a normal-strength
concrete (NC) and a high-strength concrete (HSC) mixes widely used in bridge construction …

This paper presents the findings of an investigation on early-age thermal behavior of
concrete segmental box girders using finite element (FE) analysis. A FE segmental box …

This paper investigates the mechanical behavior of perforated steel plate-concrete-filled
steel tubular (P-CFST) arch feet in concrete girder-steel arch composite bridges. A total of …

In this study, a combined finite difference and finite element model was developed to predict
the temperature development, thermally induced stresses and associated cracking risk in …

In this study, the early age thermal properties of a concrete mix containing ground
granulated blast furnace slag (GGBFS) were investigated and incorporated in a finite …

Large-scale connecting segments can provide reasonable load transition in hybrid girders,
and have been broadly used in long-span cable-stayed bridges. However, the large volume …

Three-dimensional finite element (FE) thermal and stress models were created to compute
the temperature evolution, thermal stress and potential of cracking in a segmental concrete …

Tóm tắt Recently, researches have been used Artificial Neural Network (ANN) to predict the
early-age thermal cracking of rectangle piers. But ANN has not resulted for different types of …

Engineering infrastructure includes a large number of concrete structures. The main binder
used in concrete is Portland cement, which reacts with water when mixing. During the …

Transient thermal analysis of mass concrete using ANSYS finite element program has
become popular. In ANSYS, material properties and heat generation rate of concrete are …
