Standardized Longitudinal Connection Detail For Decked Precast Prestressed Concrete Girders, Ramzi Muftah Ali Abduallah
Standardized Longitudinal Connection Detail For Decked Precast Prestressed Concrete Girders, Ramzi Muftah Ali Abduallah
Masters Theses
The use of decked precast prestressed concrete girders (DPPCG) is becoming popular in accelerated bridge construction. DPPCGs are assembled and connected on site using grout or concrete longitudinal connections. The durability performance of these connections is a concern. The objective of this research is to document the longitudinal connection behavior with respect to its design parameters, and establish a process for developing a standardized connection detail considering the demands due to live load and temperature gradient (TG) load. In order to demonstrate this process, decked bulb-tee and decked box-beam girders were considered. Finite element models, under various types and levels …
An Automated Approach To Dynamic Site Layout Planning, Duy Huu Nguyen
An Automated Approach To Dynamic Site Layout Planning, Duy Huu Nguyen
Masters Theses
Dynamic site layout planning involves determining the optimum location of resources on the construction site. Site layouts are considered dynamic because construction activities and the number and nature of associated resources change as the project progresses. Previous research has focused on the use of several algorithms to address dynamic site layout problems. These efforts do not enable automated tracking of the dynamic context of construction resources, site space and activities. This research presents an automated adaptive component level system capable of generating layouts which are optimized throughout the phases of construction projects. The system involves the integration of building information …

Cyber-Adaptive Physical Systems For Automated Construction Progress Monitoring And Asset Tracking, Syed Hammad Rasheed
Masters Theses
Despite the benefits of building information models as a means of communication, collaboration and integration in construction projects, their use is often limited to the design and tendering/bidding stage. Potential of building information models lies in its implementation during construction, operations and maintenance phases of a facility’s lifecycle. Tight Integration of building information model and physical facility by means of computational resources is required to achieve this potential such that changes in one environment are automatically reflected in the other. This is termed a cyber-adaptive physical systems approach. This research investigates the applicability of a cyber-adaptive physical systems approach in …
