Forward Osmosis Membrane Bioreactor Performance for Wastewater Treatment Applications
Global water shortage and scarcity has spurred worldwide efforts to explore alternative approaches to augment the existing water supply. Recent consideration for the utilization of wastewater as a ...
Seismic Performance of Bridge Column-Pile-Shaft Pin Connections for Application in Accelerated Bridge Construction
Bridges with integral superstructures are common in high-seismic regions. The superstructure and substructure are connected using rigid connections in these bridges. However, hinge or “pin” connections may be used to ...
Assessment of an Earthquake Resilient Bridge with Pretensioned, Rocking Columns
The seismic performance of a new bridge system is studied, tested and improved. The new bridge system: 1) reduces onsite construction time by using precast components, 2) eliminates major earthquake damage by utilizing ...
An Exploratory Experimental Evaluation of ε50 in c-ϕ soils
In this research, we explored the influence of several factors on the strain at 50% of maximum deviatoric principle stress, ε50, of c- ϕ (cohesive granular) soils. C- ϕ materials are described as Mixed Soils behaving like ...
Effect of Skew on Seismic Performance of Bridges with Seat-Type Abutments
AbstractIt is well known that skewed bridges with seat-type abutments are more vulnerable to unseating during strong earthquakes than straight bridges of the same length, due to excessive in-plane rotation. This rotation ...
Axially Loaded Drilled Shafts: LRFD Resistance Factor Calibration and Predictive Techniques for Settlement
In areas where local geology consists of unique or uncommon subsurface materials, uncertainty in deep foundation design may lead to excessive construction costs and inadequate reliability. While the calibration of area-specific ...
1-g Shake Table Experimental Evaluation of Building Settlements Founded on Liquefiable Soils
Post-disaster reconnaissance of areas affected by recent earthquakes in Japan and New Zealand has documented extensive damage to buildings with shallow foundations resulting from liquefaction-induced settlement. Current ...
Evaluating Superheavy Load Movement on Flexible Pavements: Identifying Load Nucleus and Elements of Bearing Capacity Investigation
Nowadays, industrial facilities are undergoing massive upgrades and innovations, which require moving Superheavy Loads (SHLs), these are loads with a gross vehicle weight (GVW) and axle weight exceeding the overweight legal ...
Performance Characterization of Recycled Asphalt Pavements with Warm Mix Asphalt Technologies
This study evaluated the laboratory performance characteristics of Recycled Asphalt Pavements (RAP) with Warm Mix Asphalt (WMA) Technologies. RAP was introduced in mixtures at three levels: 0, 15 and 35% of RAP contents. ...
