Enhancing Bridge Resilience And Overheight Vehicle Mitigation Through Innovative Sacrificial Cushion Systems, Aly Mousaad Aly, Marc Hoffmann 2024 LSU

Enhancing Bridge Resilience And Overheight Vehicle Mitigation Through Innovative Sacrificial Cushion Systems, Aly Mousaad Aly, Marc Hoffmann

Faculty Publications

Transportation departments have made significant strides in addressing the challenges posed by the increasing weights of trucks on bridges. While there is a growing awareness of overheight vehicle collisions with bridges, implementing effective countermeasures remains limited. The susceptibility of bridges to damage from such collisions is on the rise, further exacerbated by unpredictable lateral impact forces. This study employs nonlinear impact analysis to assess the response of an unprotected vehicle-girder model, yielding realistic deformation outcomes comparable to observed impacts on the US-61 bridge. Predictions for a truck traveling at 112.65 km/h indicate deformations of 0.229 m, 0.161 m, and 0.271 …

Factors Influencing The Occurrence Of Rework In Terms Of Risk-Based Communication Management In Construction Projects, Virani Mayniana, Rossy Armyn Machfudiyanto

Smart City

Rework in a construction project is an unplanned and unwanted activity that requires an action to repeat part or all the work to meet project standards or requirements and, in its implementation, causes increased work, time, and costs. Based on previous studies that discuss the factors that cause rework, poor communication management or coordination between stakeholders is one of the causes of rework. Therefore, a literature study was conducted to identify project communication management risks that allow rework to occur and resulted in 54 communication management risk factors. Furthermore, the results of the literature study were validated by experts who …
