Pressure-Equalized Rainscreen Wall System: A Full-Scale Experiment, Samar D. Dernayka
Digitized Theses
The pressure equalized rainscreen wall, considered as the most effective building envelope against wind induced rain penetration, requires continuous investigations to reach better performance. This research seeks the optimum pressure equalization process under external pressure conditions and wall parameters that have not previously been studied in detail. For this purpose, a single compartment full-scale wall model was built in a controlled facility at the University of Western Ontario. The cavity pressure response to external fluctuations was experimentally examined with respect to the rainscreen venting area ratio, under two types of real wind pressure distributions generated mechanically at zero degree incidence: …

Optimum Design Of Cable-Stayed Bridges, Mahmoud M. Hassan
Digitized Theses
Owing to their excellent structural characteristics, aesthetic appearance, low maintenance cost, and efficient use of structural materials, cable-stayed bridges have gained much popularity in recent decades. Stay cables of a cable stayed bridge are post-tensioned to counteract the effect of the bridge dead load. The solution for an optimum distribution of post-tensioning cable forces is considered one of the most important and difficult tasks in the design of cable-stayed bridges. A novel approach that utilizes the finite element method, B-spline curves, and real coded genetic algorithm to determine the global optimum post-tensioning cable forces is developed. The effect of geometric …
