Since. the mid-2000s the Ministry of Transportation (MTO) Northwestern Region has been actively researching, investigating, and implementing accelerated bridge construction (ABC) COMPARISON OF DEFLECTION AND VIBRATION Research and development efforts in the early 1990s led to the introduction of High Performance Steel (HPS), which is available today in yield strengths of 50 ksi, 70 ksi, and 100 ksi. Bridge owners and designers quickly recognized the benefits of this material for its high strength-to-weight ratio, toughness, weldability, and increased

CROSS-SECTIONAL COMPACTNESS AND BRACING

cross-sectional compactness and bracing requirements for hps483w girders An evaluation as to the appropriateness of using the current American building and bridge specification (according to AASHTO 1998 and AISC 1999) provisions for cross-sectional compactness and adequate bracing is carried out within the context of flexural applications involving A709 Gr. HPS483W high performance steel I Calibration of Strength Reduction Factor for Reinforced Oct 10, 2020 · Ultra-high-performance concrete (UHPC) has been widely used in bridges and other structures throughout the world. However, very limited studies have been carried out to address the strength reduction factor for reinforced UHPC girders in flexure.

High performance steel bridge girder compactness. Christopher Earls, Bhavin Jitendra Shah; Engineering; 2002; Abstract The present study employs experimentally verified nonlinear finite element modeling techniques for the study of high performance steel (HPS) I-shaped bridge girders. Cross-Sectional Compactness and Bracing Requirements for Current American steel building and bridge design specifications (AISC 1999, AASHTO 1998) simplify the flexural design of both homogeneous and hybrid I-shaped members by treating local and global inelastic stability phenomenon independently. According to both specifications, if a homogeneous or hybrid section is compact and sufficiently braced against lateral instability, the member will Cross-Sectional Compactness and Bracing Requirements for The flexural behaviors of composite I-girders made of a high performance steel, HSB690, having a yield strength of 690 MPa in negative moment, were numerically investigated by applying an

Development of a Structurally Optimized Ultra-High

The characteristics of ultra-high performance concrete (UHPC) are particularly well suited to the structural and environmental challenges that are placed on every highway bridge. Specifically, the compressive strength allows for high levels of prestressing, and the tensile strengths allow for reduction or elimination of mild (i.e., shear Flexural Strength of Composite HSB690 I-Girders in Abstract. The flexural behaviors of composite I-girders made of a high performance steel, HSB690, having a yield strength of 690 MPa in negative moment, were numerically investigated by applying an incremental ultimate strength analysis with material and geometrical nonlinearities. HIGH-PERFORMANCE STEEL BRIDGE DESIGN AND COST COMPARISONSHIGH-PERFORMANCE STEEL BRIDGE DESIGN AND COST COMPARISONS. High-performance steel (HPS) is a relatively new and promising material for steel girder bridges. Several studies have been conducted regarding HPS, its properties, and its potential future use. The many benefits of HPS include its increased strength, the lighter structures that can be

Innovative lateral bracing of high performance steel

High performance steel (HPS) is steel with a yield strength of 485 MPa (70 ksi) or more. High performance steel is expected to have better weldability, ductility, and fracture toughness than other high yield strength steels. A girder designed using high performance steel would be smaller and lighter Local buckling behavior of high strength steel welded I Earls, CJ, Shah, BJ (2002) High performance steel bridge girder compactness.
