Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano

Architectural Engineering

As cross-laminated timber has become an increasingly popular construction material, its use as a shear wall element has also demanded attention. Primary obstructions to the use of CLT shear walls have been the lack of an economic connection type that does not compromise the structural integrity and has the robustness that CLT shear wall panels deserve. Dovetail connections provide a great option for the connection of CLT shear walls. With more experimentation, the optimal dovetail geometry can be further developed. The small-scale testing done in conjunction with this report proved that very deep pins and tails will result in bearing …

Unexpected Setbacks When Excavating – Using Gpr For Mitigating Risk: A Case Study, Samuel L. Marcum

Construction Management

Whether constructing on undeveloped land or on an existing developed site, there is a risk of encountering unexpected objects when excavating. With today’s technology in Ground Penetrating Radar (GPR), this risk can generally be mitigated. Using Whiting-Turner’s construction of Stanford University’s new ChEM-H & SNI Building as an example, this case study discusses the use of GPR for underground mapping, as well as various ways to implement GPR technology. The ChEM-H & SNI site had many underground utilities that required precise pot-holing to verify locations. Although pot-holing is widely used, it is a destructive method, it is time and labor …

High Performance Mortar With 100% Recycled Aggregate Using Titanium Dioxide Nanoparticles, Molly Schrager, Vito Francioso, Arjun Kadakia, Mirian Velay-Lizancos

The Summer Undergraduate Research Fellowship (SURF) Symposium

Concrete and mortar are materials commonly used in construction. Their main compounds are cement, aggregates (sand and gravel) and water. In an effort to increase the sustainability of these materials, the idea of using recycled aggregates from ground old concrete and using it to make mortar and concrete has gained more interest. It has two advantages: it reduces the need to mine for raw materials and lessens the amount of old and defective concrete that is typically put in landfills. But, the use of recycled concrete aggregate lowers the strength of mortars and concretes because the residual compounds in the …

Man Vs Car: The Ultimate Clash Designing A Safer Walking Experience For Las Vegas Pedestrians, Jenn Wong

Hospitality Design Graduate Student Capstones

The car has become a common weapon of choice for terrorists and others hoping to do harm to unsuspecting pedestrians. There is a pressing need for the development of effective, preventive design strategies to stop vehicular attacks before they cause pedestrian fatalities. Vehicular violence has broader consequences beyond the pedestrians directly involved in specific incidents. The fear created by vehicular attacks undermines public trust and unity, resulting in harm that is less obvious than the immediate casualties, but is just as damaging. Is it possible to design the fear away? Do street safety devices enhance pedestrians feelings of safety?
