A finite element-finite difference numerical model is developed for predicting non-uniform temperature development in hydrating concrete with respect to time and space. The results obtained from this model can be used by structural and construction engineers to predict critical thermal stresses induced due to differential temperatures between the core and the surface of the concrete at early ag...

The study presented in this paper analyzed four long-term pavement performance (LTPP) test sections located the states of New York (NY) and California (CA). Two them are flexible sections, whereas other two composite sections. levels analysis—in-state analysis cross-state analysis—were performed for these to determine impacts traffic climate conditions. was evaluated respect thermal cracking ru...

This paper explores the effects o f adding synthetic reinforcing fibres to highstrength reinforced concrete columns and in particular only to the cover o f the columns. An experimental program was conducted where seven circular reinforced concrete columns were tested with varying fibre content one contained no fibres, two contained fibres throughout the cross-section and four contained fibres o...

A comprehensive computational model to simulate the nonlinear seismic response of composite frames with rectangular concrete-filled steel tube (RCFT) beam-columns and steel girders and braces is presented in this work. A three-dimensional fiber-based distributed plasticity mixed finite element formulation is introduced. The finite element formulation of RCFT beam-columns was derived with separa...

The improper disposal of used frying oil (UFO) presents numerous ecological, environmental and municipal problems. Of great concern is the resultant blockage of municipal drainage systems and water treatment facilities, harm to wildlife when they become coated in it and detriment to aquatic life and ecosystems due to the depletion of the oxygen content in water bodies such as rivers and lakes t...

Several agro-waste materials have been utilized for sustainable engineering and environmental application over the past decades, showing different degrees of effectiveness. However, information concerning wider use palm oil clinker (POC) its performance is still lacking. Therefore, as a solid waste byproduct produced in one processing stages, generating huge quantity mostly dumped into landfill...

The recyclability of waste cooking oil (WCO) as rejuvenator for aged asphalt mixture improved the serviceability pavement itself. Currently, researcher is exploring new potential WCO modifier binder modification. However, issue compatibility properties in modification with arises since poor mechanical performance globally recorded thus reflected weakness adhesion bonding inside material. Basica...

This paper presents the development and properties assessment of braided reinforced composite rods (BCR) able to both reinforce and monitor the stress state of concrete infrastructures. The research study aims at understanding the tensile behaviour and self-monitoring ability of composite rods reinforced by a textile structure braided structure with core reinforcement for civil engineering appl...

Vaporization of fission products and certain other materials is estimated for the extreme environmental conditions projected for severe reactor accidents. Partial pressures of gaseous species are calculated from thermochemical data or estimates. Mounts of vapor transported material are evaluated from projected gas flows during two phases of a hypothetical accident--( a) core dry out phase and (...
