Seismic Performance of Circular and Interlocking Spirals RC Bridge Columns Under Bidirectional Shake Table Loading
Under seismic excitations reinforced concrete bridge columns (RCC) are subjected to combinations of forces and deformations. These complex actions are caused by spatially-complex variation of earthquake ground motions, the ...
Root-Induced Compaction and its Effects on Soil Microstructure and Soil Hydraulic Properties Using X-ray Micro-Tomography and Numerical Simulations
Soil is a challenging environment where resources, such as water, nutrients and air, are scarce and patchy. Plants and soil microorganisms have limited ability to move toward nutrient-enriched zones, compared with animals. ...
Evaluation of New and Existing Test Methods to Assess Recycled Asphalt Pavement Properties for Mix Design
The use of reclaimed asphalt pavement (RAP) in flexible pavement surface layer has been a major sensitive issue in the construction industry. Due to limited space available in landfills, the decline in the amount of high ...
Delay Models at Signalized Intersections Considering Short Right-Turn Lanes and Right Turn on Red
The most widely used procedures for estimating delay at signalized intersections are provided by the Highway Capacity Manual (HCM). Despite many revisions, the current HCM delay models lack consideration of short turn lanes ...
Seismic Response of Precast Bridge Columns with Energy Dissipating Joints
Accelerated bridge construction (ABC) is attractive in congested urban areas and environmentally sensitive regions because it minimizes traffic delays and construction site safety risk. Precast bridge components are an ...
