Abstract: The operation of reinforced concrete structures is directly associated with the adhesion between the steel bar and the concrete, which allows the internal forces to be transferred to the reinforcement during the process of loading the structural elements. The modification of the concrete composition, with the introduction of recycled aggregate from construction and demolition waste (CDW), affects the steel-concrete interface and can modify the...

Abstract: The use of cool materials on the building envelope is one of the most cost-effective ways to increase indoor thermal comfort conditions in hot climates and decrease the cooling energy needs. Despite the benefit of reducing cooling loads, researches have demonstrated that aging of roof coatings changes the initial solar reflectance (SR), which influences the long term building thermal and energy performance. Thus, this work presents preliminary... More

Abstract: When the bridge components needing maintenance are the world problem at present, and the health monitoring system is considered to be a very helpful tool for solving this problem. In this paper, a large number of strain data acquired from the structural health monitoring system (SHMS) installed on a continuous rigid frame bridge are adopted to do reliability assessment. Firstly, a calculation method of punctiform time-dependent reliability is... More

Abstract: Many theories in sociology and psychology encourage people to maintain and contact with nature. Biophilia, for instance, examines the connection between humans and nature within the built environment. It is considered one of the solutions to human isolation from nature, especially in the workplace. This study examined the factors of employee's awareness and preference that affect biophilia application at the workplace. This study's primary data... More

Abstract: Augmented Reality (AR) applications can be used to improve tasks and mitigate errors during facilities operation and maintenance. This article presents an AR system for facility management using a three-dimensional (3D) object tracking method. Through spatial mapping, the object of interest, a pipe trap underneath a sink, is tracked and mixed onto the AR visualization. From that, the maintenance steps are transformed into visible and animated... More

Abstract: Apart from many advantages, High Strength Concrete (HSC) has disadvantages in terms of brittleness and poor resistance to fire. Various studies suggest that when polypropylene (PP) fibers are uniformly distributed within concrete, they play an active role in improving spalling resistance of concrete when exposed to elevated temperature while having no adverse effect on its mechanical properties. Therefore, there is a necessity to quantify the... More
