RISCost-Efficient Procurement of Bridge Infrastructures by Incorporating Life-Cycle Cost Analysis with Bridge Management Systems
Publisher: American Society of Civil Engineers
Abstract: Life-cycle cost analysis (LCCA) has recognized potential for rationalizing bridge procurement, but its use in this context is far from systematic. The integration of LCCA findings in decisions is often far from robust. ...
Evaluation Procedure for Mutually Exclusive Highway Safety Alternatives under Different Policy Objectives
Publisher: American Society of Civil Engineers
Abstract: The purpose of evaluating mutually exclusive alternatives is to select the one with the most benefits for implementation. A number of analytic techniques are available for such evaluation purposes. This paper discusses ...
Damage Analysis of Concrete Open-Spandrel Deck Arch Bridges under Seismic Loads
Publisher: ASCE
Abstract: Risk assessment of arch bridges can be beneficial for making informed choices following an earthquake by addressing the most vulnerable components. Although several researchers have studied the seismic vulnerability of ...
Influence of Pore Water on the Fracture of Silica Sand at Particle Scale
Publisher: American Society of Civil Engineers
Abstract: The fracture of particles has a significant influence on the engineering behavior of granular materials. There are no reported conclusive answers in the literature to explain the influence of pore water on the fracture of ...
Full Dynamic Analysis of Offshore Platform Structures Using Exact Timoshenko Pipe Element
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the major divisions in the mathematical modeling of a tubular structure is to include the effect of the transverse shear stress and rotary inertia in vibration of members. During the ...
Mechanisms for Transportation Infrastructure Investment in Developing Countries
Publisher: American Society of Civil Engineers
Abstract: In this paper, the writers examine different investment mechanisms for transportation infrastructure projects involving the private enterprise in developing countries. Roles identified vary from those of a financier to an ...
Analysis of Techniques Leading to Radical Reduction in Project Cycle Time
Publisher: American Society of Civil Engineers
Abstract: Today’s construction business relies on first-to-market product strategies to gain competitive advantages and increase profit margins. This has created an increased demand for a high performance capital project delivery ...
Decision Tool for Selecting the Optimal Techniques for Cost and Schedule Reduction in Capital Projects
Publisher: American Society of Civil Engineers
Abstract: Projects must meet budget, schedule, safety, and quality goals to be regarded as a success. Many factors come into play, and many decisions are made that influence a project’s outcome. Today, owners are often faced with ...
Effects of Bed Material and Downstream Flow Depth on the Evolution of Bed in a Right-Angled Open-Channel Confluence
Publisher: ASCE
Abstract: Effects of bed material and downstream flow depth on bed evolution in a right-angled channel confluence were studied through laboratory experiments. Velocity field, water surface elevation, and bed profile were measured ...
Improving Lithium-Ion Battery Pack Diagnostics by Optimizing the Internal Allocation of Demand Current for Parameter Identifiability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article optimizes the allocation of external current demand among parallel strings of cells in a lithium-ion battery pack to improve Fisher identifiability for these strings. The article is motivated by the fact that ...
