Thermal Stability of Latex Modified Mortars Containing CNTs

Durability of concrete and cementitious materials has been of a great concern to the construction industry in the last two decades due to the deterioration of large number of concrete structures which were built in the 60 and 70 s. Among different environmental conditions, the continuous exposure to freeze–thaw and thermal fatigue cycles remains one of the most aggressive...

Numerical Analysis of Pile–Soil Interaction under Axial and Lateral Loads

Yasser Khodair Ahmed Abdel-Mohti p Khy In this paper, the analysis of a numerical study of pile-soil interaction subjected to axial and lateral loads is presented. An analysis of the composite

Analysis, prediction, and case studies of early-age cracking in bridge decks

Early-age cracking can adversely affect strength, serviceability, and durability of concrete bridge decks. Early age is defined as the period after final setting, during which concrete properties change rapidly. Many factors can cause early-age bridge deck cracking including temperature change, hydration, plastic shrinkage, autogenous shrinkage, and drying shrinkage. The cracking...

Analytical investigation of pile–soil interaction in sand under axial and lateral loads

This paper presents a numerical study of pile–soil interaction due to application of axial and lateral loads to piles in sand. The pile–soil interaction was analyzed using the finite difference (FD) software LPILE and two finite element (FE) software. The three-dimensional (3D) FE models of pile–soil interaction have been created using Abaqus/Cae and SAP2000. Various types of...

Assessment of seismic performance of skew reinforced concrete box girder bridges

The seismic vulnerability of highway bridges remains an important problem and has received increased attention as a consequence of unprecedented damage observed during several major earthquakes. A significant number of research studies have examined the performance of skew bridges under service and seismic loads. The results of these studies are particularly sensitive to modeling...

Investigation of Likelihood of Cracking in Reinforced Concrete Bridge Decks

One of the biggest problems affecting bridges is the transverse cracking and deterioration of concrete bridge decks. The causes of early age cracking are primarily attributed to plastic shrinkage, temperature effects, autogenous shrinkage, and drying shrinkage. The cracks can be influenced by material characteristics, casting sequence, formwork, climate conditions, geometry, and...
