RISReview of <i>Information-gap decision theory: Decisions under severe uncertainty</i> by Yakov Ben-Haim
Publisher: American Society of Civil Engineers
Buckling of Elastic Columns Using Convex Model of Uncertain Springs
Publisher: American Society of Civil Engineers
Abstract: A procedure is described for evaluating the buckling load of weightless prismatic columns with uncertain rotational spring elements. The uncertainty in the spring elements is expressed in terms of a nonprobabilistic convex ...
Resilient Posttensioned Bridge Bent with Buckling Restrained Brace
Publisher: ASCE
Abstract: A new method for building seismically resilient bridges is investigated using Accelerated Bridge Construction (ABC) technologies. A hybrid two-column bridge bent with posttensioned precast concrete columns and a diagonal ...
Self-Centering Bridge Bent with Stretch Length Anchors as a Tension-Only Hysteretic Hybrid System
Publisher: ASCE
Abstract: Accelerated bridge construction (ABC) incorporates innovative techniques to reduce construction time and traffic disruption. The objective of the research was to design, build, and test a seismically resilient bridge bent ...
Seismic Retrofit of Reinforced Concrete Moment Frame Using a BRB with U-Plate Connections
Publisher: ASCE
Abstract: Since their first use in 1989, buckling-restrained braces (BRBs) have proven to be an efficient energy dissipation device. Two reduced scale quasi-static cyclic experiments were conducted for a reinforced concrete (RC) ...
Experiments and Numerical Analysis of a Seismically Resilient Bridge Bent with Stretch Length Anchors as Energy Dissipators
Publisher: ASCE
Abstract: The experimental performance and numerical analysis of a hybrid two-column bridge bent was examined to evaluate its ability to self-center and dissipate hysteretic energy during earthquakes. The experiment was conducted ...
Cyclic Tests and Analysis of Corroded Precast Concrete Column-to-Footing Connections Constructed with Accelerated Bridge Construction Methods
Publisher: ASCE
Abstract: The objective of this research is to evaluate numerically and experimentally the cyclic performance of corroded columns constructed with accelerated bridge construction (ABC) methods. Three column-to-footing specimens were ...
Seismic Performance of Self-Centering Post-Tensioned Concrete Columns Reinforced with Steel–GFRP Bars and GFRP Spirals
Publisher: American Society of Civil Engineers
Abstract: A novel concept of hybrid reinforcement in the form of glass fiber‒reinforced polymer (GFRP) longitudinal column bars combined with steel longitudinal column bars and high-strength post-tensioning all-threaded rods is ...
Design of Trusses Under Uncertain Loads Using Convex Models
Publisher: American Society of Civil Engineers
Abstract: The optimal design of trusses subjected to loads considered to be uncertain in both magnitude and direction is investigated. A non-probabilistic ellipsoidal convex model is established for considering the uncertainties ...
Confinement Model of Concrete with Externally Bonded FRP Jackets or Posttensioned FRP Shells
Publisher: American Society of Civil Engineers
Abstract: A design-oriented confinement model for square and rectangular columns confined with bonded fiber-reinforced polymer (FRP) jackets, and shape-modified square and rectangular sections confined with posttensioned FRP shells ...
