Soil-bridge interaction during long-duration earthquake motions

Creator:: Romney, Kyle T.
Abstract:: Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...

Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:: Amneus, Deanna
Abstract:: Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...
