Hard Hat Safety By California Contractors, Jonathan G. Hernandez
Construction Management
The hard hat is the quintessential item of PPE, and yet it often gets overlooked when ensuring safety standards are being met. We all expect our hard hat to protect us, but many never inspect it to ensure that it is properly fulfilling its purpose. This disregard to inspection and maintenance can lead to serious injury or death in the event of an accident. While organizations such as OSHA and the hard hat manufacturers themselves post information on this topic, it is unclear if this information is actually being received by the people involved in a construction project. This research …

Improving Ductility Of Slender Reinforced Concrete, Luke M. Ostrom
Construction Management
The Sylmar earthquake of 1971 caused significant damage to slender, non-ductile reinforced concrete (RC) shear wall buildings in California. A later survey by the Concrete Coalition in 2011, under the guidance of members of the Earthquake Engineering Research Institute (EERI), indicated that there are over 3000 vulnerable concrete buildings in California [8]. This led to City of Los Angeles (LA) Ordinance 193893 enacted in 2015, which requires mandatory upgrades to these concrete buildings by 2035. Current practice to meet the requirements of this ordinance, with respect to RC wall buildings, involves adding new shear walls to the building plan or …

In-Situ Mechanical Characterization For Compacted Aggregates, Douglas Cortes, Paola Bandini
In-Situ Mechanical Characterization For Compacted Aggregates, Douglas Cortes, Paola Bandini
Publications
The evaluation of compacted unbound aggregate layers is perhaps the most common undertaking in transportation-related projects. The assessment of compaction compliance in engineered fills, subgrades, subbases, and bases in roadways and railways is central to ensure longevity of ground transportation infrastructure. In many cases, premature failures in roadways that originate in the unbound aggregate layers can be traced back to inadequate compaction. These failures are preventable, provided the problem areas can be identified by a suitable field test during construction. The most widely used method for compaction assessment during construction is the nuclear density gauge (NDG) test. While the device …

On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo
On Thermal Bowing Of Concrete Sandwich Wall Panels With Flexible Shear Connectors, Fray Pozo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Thermal bowing, often referred as bulging or out-of-plane wall deflection, is a common issue on sandwich panel walls caused by a temperature differential between a building interior temperature and the environment. The stresses caused by temperature changes in concrete members are widely known in the practice of bridge design, but not on sandwich wall panels. For sandwich wall panel applications, it is common to have non-composite panels when the designer expects a high temperature gradient, what yields a less economical design, but reduces the bowing.
This project aimed to validate current assumptions regarding the heat flow in sandwich wall panels …
