MPC Research Reports
View AllThis study proposes a new remote sensing technique to measure three-component (3C) dynamic displacement of three-dimensional (3D) structures. A sensing system with an unmanned aerial vehicle (UAV) platform and contact-free sensors (e.g., optical and infrared (IR) cameras) was employed to provide a portable... Escherichia coli (E. coli) is often used as an indicator organism to quantify the microbial safety of natural water resources. E. coli in stormwater runoff can cause serious health risks in natural water bodies. Conventional stormwater best management practices are generally not effective at removing... This report presents the behavior of reinforced concrete beams retrofitted with carbon fiber reinforced polymer (CFRP) sheets and ultra-high performance concrete (UHPC) jackets in a multi-hazard environment. Following the procedural protocol of a published standard, the beams are cyclically loaded under... In recent years, major initiatives have been taken to replace non-renewable materials with environmentally friendly and sustainable ones. The present study was undertaken to apply a scalable process for laboratory production of cellulose nanofibers (CNF) and to evaluate the feasibility of using the produced... Pavements in cold regions of the United States undergo significant accumulation of snow and ice on their surfaces during the extended winter season, leading to reduced skid resistance and increased traffic crashes. Deicers, such as sodium chloride, calcium chloride, and magnesium chloride, have been... Recently, significant advances have been made in the development of rapid setting cementitious materials for partial-depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed.... With the development of accelerated bridge construction (ABC), the seismic performance of typical ABC column-footing connections has been evaluated in high earthquake-prone states, like Utah, California, Nevada, and Idaho. But to date, the current literature has yet to fully examine the impact behavior... The maintenance and upgrade of infrastructure and buildings are critical for ensuring their performance, safety, and minimizing costs. However, inadequate planning and budget allocation, as well as resource constraints, often result in delayed maintenance, leading to costly interventions. To address... With the popularization of accelerated bridge construction (ABC), the utilization of splice sleeve connections has been researched to determine their performance using a variety of connection details and under several loading scenarios. However, fundamental research on the load distribution and load... This report presents the relevancy of the allowable stress rating (ASR) and the load and resistance factor rating (LRFR) methods for timber bridges. Benchmark bridges constructed in the 1930s have been upgraded with hollow structural steel (HSS) beams and three-dimensional finite element models provide... |
