Dissecting The Safety Benefits Of Protected Intersection Design Features, Nicholas Campelll Jan 2019

Dissecting The Safety Benefits Of Protected Intersection Design Features, Nicholas Campelll

Transportation Engineering Masters Projects

Protected intersections are an integral component of Complete Street networks and are used to facilitate and delineate the route cyclists should take while traveling along a protected network. The separation from the travel lane of automobiles, however, causes a decrease in driver attentiveness to cyclists. Rates of incidents of cyclists, specifically with right turning vehicles, have increased in recent years, leading to a desire to improve the safety benefits of existing protected intersections to increase the visibility of cyclists and driver awareness. This research used a simulated environment to test the effectiveness of different pavement markings and intersection radii on …


Nonlinear Fastener-Based Modeling Of Cold-Formed Steel Shear Walls Under Lateral Loads, Fani Derveni Jan 2019

Nonlinear Fastener-Based Modeling Of Cold-Formed Steel Shear Walls Under Lateral Loads, Fani Derveni

Structural Engineering Masters Projects

As cold-formed steel (CFS) has increasingly been used in low- and mid-rise construction across United States, it becomes necessary to capture and evaluate its lateral response in both, sub-system/member level and system level. The main lateral resisting system in cold-formed steel construction is shear walls; shear walls are the focus of this work. In particular, the present study aims to shed light on the response of wood sheathed coldformed steel (CFS) shear walls exposed to earthquake events through nonlinear high fidelity fastener-based modeling. The numerical approach is fastener-oriented including nonlinear experimental-determined connector elements for steel-to-sheathing connections, orthotropic oriented strand board …
