Collapsed-RC Building Failure Mechanisms with a Forensic Engineering Approach
(ASCE, 10/1/2020 )A reinforced concrete building in Konya, Turkey, collapsed suddenly on February 2, 2004, and 92 residents died. This case study was performed to determine the alternate load paths and failure mechanism of the building. The ... -
Failure Investigation and Sustainable Renovation for Slope at National Chi Nan University in Taiwan
(ASCE, 10/1/2020 )On September 21, 1999, at 1:47 a.m., Taiwan was shaken by a magnitude 7.3 Chi-Chi earthquake, the most severe one on this island in the past 100 years. The National Chi Nan University (NCNU), located in Puli, ... -
Vibration Serviceability Evaluation of Office Building Floors Due to Human Movements
(ASCE, 8/1/2020 1)The tendency of architects and engineers to reduce construction costs by using high-strength, lightweight materials, and owners’ requirements for large open spaces, along with the new trend in the use of paperless or ... -
Exploratory Study of Nondestructive Parallel Seismic Testing Challenges in Estimating the Depth of Unknown Wood Bridge Foundations
(ASCE, 6/1/2020 1)Nondestructive methods have been extensively used to characterize unknown bridge foundations. Among various nondestructive methods, conventional and reverse parallel seismic (PS) methods are considered proper methods capable ... -
Discharging Compacted Sediment by Underwater Blasting in Conjunction with a Desilting Tunnel in the Tseng-Wen Reservoir of Taiwan
(ASCE, 6/1/2020 1)Sediments transported by heavy rainfall result from frequent typhoons in the Tseng-Wen reservoir, which now comprise one-third of the capacity of the reservoir. Yearly increases of 6.56 million m3 deposits are planned for ... -
Experimental Investigation on Wear Resistance of Bushing in Bridge Suspenders
(ASCE, 6/1/2020 1)A pin connection is often used to join the hangers with the main cable and main girder in a suspension bridge. As the bridge moves under live or wind loads, the pin-connection components are subject to repetitive loading. ... -
Modeling Failure of Oil Pipelines
(ASCE, 2/1/2020 1)As the safest means of transporting gas and hazardous materials, pipelines transport invaluable petroleum material. However, a considerable number of accidents have happened involving these facilities, leading to economic ... -
Field Testing of Wind Turbine Towers with Contact and Noncontact Vibration Measurement Methods
(ASCE, 2/1/2020 1)Wind turbine tower vibration parameters are critical for design and maintenance of wind farms. In this paper, measurement campaigns of two in-service 65-m tall wind turbine towers are investigated. Different field vibration ... -
Monitoring Dynamic Properties of a Pres-Lam Structure: Trimble Navigation Office
(ASCE, 2/1/2020 1)Pres-Lam technology relies on unbonded post-tensioning tendons to provide moment capacity to timber beam-column, wall-foundation, or column-foundation connections. When designing buildings for high-seismic-risk areas, ... -
Depth Evaluation of Submerged Pile Bents
(ASCE, 2/1/2020 1)Developing an appropriate and efficient inspection pattern for an unknown bridge substructure is a critical issue for bridge engineers, contractors, and bridge agencies. This paper introduces a two-phase near-surface ... -
Preventive Interface Management for Design-Build Wireless Train Control Mass Rapid Transit Projects
(ASCE, 2/1/2020 1)Traditional interface design integration for a mass rapid transit (MRT) project focuses on the integration needs of specified interface requirements among civil and electrical and mechanical (E&M) subsystems. This ... -
Statistical Forecasting of Bridge Deterioration Conditions
(ASCE, 2020)The United States has more than 615,000 bridges. US national bridge inspection standards developed by the Federal Highway Administration (FHWA) require routine inspections of these bridges every 24 months regardless ... -
Computer Vision–Based Human Comfort Assessment of Stadiums
(ASCE, 2020)In this article, a new measurement method for human comfort assessment levels for stadiums is proposed and demonstrated. The method is based on a specific computer vision and image processing algorithm called optical flow. ... -
Finite-Element Model Updating and Dynamic Responses of Reconstructed Historical Timber Bridges using Ambient Vibration Test Results
(ASCE, 2020)Historical timber bridges are significant cultural structures and have a long tradition. There are many pre-1950s bridges still in use today. In recent years, great resources have been devoted to the restoration of historical ... -
Forensic Inquiry into Derailment of a Launching Gantry
(ASCE, 2020)Bridge building entails considerable risk, as attested to by the relatively frequent occurrence of worksite accidents. In the accident reported on here, an overhead gantry derailed during the construction of the last of ... -
Buckling Capacity of Socket-Template Scaffold System without X-Bracing
(ASCE, 2020)Socket-template steel scaffolds are supporting scaffolds that are commonly used in construction to support the gravity load of floor slabs. The buckling behavior of the overall scaffold is remarkably influenced by the ... -
Mitigating Risk of Confined Explosion via Lightweight Sacrificial Cladding
(ASCE, 2020)A confined explosion inside a critical facility may lead to the total paralysis of pertinent operations. Practical solutions to mitigate such risk include lightweight sacrificial cladding, which can be deployed as a physical ... -
Early-Age Behavior of Internally Cured Concrete Bridge Deck under Environmental Loading
(ASCE, 2020)The early-age cracking of bridge decks is a typical issue in the US that reduces service life. Internally cured (IC) concrete has been used in some states to reduce or eliminate the development of cracks in reinforced ... -
