Design And Probabilistic Analysis Of Mid- And High-Rise Wood Buildings Subjected To Earthquake Excitations, Shucheng Yang
Design And Probabilistic Analysis Of Mid- And High-Rise Wood Buildings Subjected To Earthquake Excitations, Shucheng Yang
Electronic Thesis and Dissertation Repository
Mass timber products, such as the glulam or cross laminated timber (CLT), are less frequently used construction materials at present for mid-rise and high-rise buildings. The feasibility and possible advantages of applying timber materials for constructing mid- and high-rise buildings are under investigation. One of the issues that needs to be addressed for the use of heavy timber materials is the safety of such constructions under seismic excitations. To address this issue, the nonlinear inelastic seismic responses and capacity curves of a wood buildings must be assessed. For this, the 10-, 15- and 20-storey buildings are designed using heavy timber …
Numerical Modeling Of Tornado-Like Vortex And Its Interaction With Bluff- Bodies, Zoheb Nasir
Numerical Modeling Of Tornado-Like Vortex And Its Interaction With Bluff- Bodies, Zoheb Nasir
Electronic Thesis and Dissertation Repository
The study the flow structure of tornado-like vortices and their impact over engineering structures is important due to the extent of tornado induced fatalities and damages observed each year in North America and around the world. In the present study, a numerical modeling approach inspired by the WindEEE Dome and the modified version of Ward’s Tornado Simulator has been developed. Using a full-scale numerical simulator, tornadoes of different intensities have been simulated for different swirl ratio values to study flow structures in comparison with previous studies. The effect of topographic features on the tornado-like vortex has been investigated for the …

Numerical Modelling Of Downburst Interaction With Bluff Body, Aditi Jog
Electronic Thesis and Dissertation Repository
The objective of this study is to investigate the interaction of a bluff body with a downburst flow. Numerical investigation of the flow field using CFD analysis was carried out for three different downburst sizes (h/d=1, 2, 4) under suitable boundary conditions subjected to constant jet velocity. The downburst-structure interaction study was conducted for two jet diameters (h/d=1 and 4) and two radial locations from the downburst center.
The results showed that the downburst size greatly dominates the intensity of the flow. The largest downburst resulted in the highest velocity magnitude near the ground and also covered a larger area …
