RISDerivation of a General Reflection Coefficient of Blast-Loaded Buried Structures
Publisher: American Society of Civil Engineers
Abstract: A general reflection coefficient (GRC) is defined to determine the equivalent uniform stress on an underground arched structure subjected to a subsurface explosion. The single-degree-of-freedom model approach is adopted ...
Maximum Impact Force of Truck Frontal Crashing into Antiram Bollard Systems
Publisher: American Society of Civil Engineers
Abstract: Antiram bollard systems (ABSs) can effectively prevent vehicle bombs from approaching protected buildings and infrastructures and thus reduce the damage from blast and debris. This paper presents an assessment of existing ...
Investigation on Postfire Residual Capacity of High-Strength Steel Columns with Axial Restraint
Publisher: ASCE
Abstract: This paper experimentally and analytically investigates the fire and postfire behavior of axially restrained high-strength steel columns. Tests on the buckling behavior during heating as well as the residual load-bearing ...
Dynamic Effects on Steel Frames with Concrete Slabs under a Sudden Edge-Column Removal Scenario
Publisher: ASCE
Abstract: The dynamic effect of structures under column removal scenarios is investigated by conducting comparative experiments on two identical steel frames with concrete slabs. One frame suffers from a static edge-column loss, ...
Temperature Calculation Method for Hanger Systems Exposed to Multigrade Vehicle Fires
Publisher: American Society of Civil Engineers
Abstract: Extensive vehicle fires threatening suspension bridges in the last decade have aroused an emerging demand to estimate the fire safety of hanger systems. One of the paramount tasks for evaluating the fire resistance of ...
Approach for Modeling Fire Insulation Damage in Steel Columns
Publisher: American Society of Civil Engineers
Abstract: This paper presents an approach for modeling the fire insulation damage in steel columns. Both experimental and numerical studies were carried out to investigate the failure pattern and damage phenomenon of fire insulation ...
Experimental Studies on Progressive Collapse Resistance of Steel Moment Frames under Localized Furnace Loading
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental studies on the performance of planar moment steel frames with one column heated. The novelty of these tests is that the influences of key stages in the response of the heated column under ...
Introducing the new generation of Chinese geostationary weather satellites – FengYun 4 (FY-4)
Publisher: American Meteorological Society
Abstract: hina is developing a new generation of geostationary meteorological satellites called FengYun-4 (FY-4) which is planned for launch beginning in the 2016 timeframe. Following upon the current FY-2 satellite series, FY-4 ...
Behavior-Based Resistance Model for Bearing-Type Connection in High-Strength Steels
Publisher: ASCE
Abstract: This paper investigates the bearing resistance of bolted connections with consideration of bolt hole elongations. Based on the test results of 27 single-bolt connections and 36 two-bolt connections fabricated from three ...
Development of Pressure-Impulse Diagrams for Framed PVB-Laminated Glass Windows
Publisher: American Society of Civil Engineers
Abstract: This paper investigates isodamage criteria for framed PVB (polyvinyl butyral) laminated glass panels subjected to blast load. Isodamage criteria are presented in the form of pressure-impulse (P-I) diagrams, and a methodology ...
