RISAccurate Methods for Elastic Seismic Demand Analysis of Reinforced Concrete Walled Buildings
Publisher: American Society of Civil Engineers
Analytical Performance Simulation of Special Concentrically Braced Frames
Publisher: American Society of Civil Engineers
Abstract: The properties of special concentrically braced frames (SCBFs) enable them to be designed to meet performance-based seismic design (PBSD) criteria. SCBFs have large stiffness and strength to meet serviceability performance ...
Design of Cotton Duck Bridge Bearing Pads
Publisher: American Society of Civil Engineers
Abstract: Bearings are used to support loads and accommodate movements in bridges. Cotton duck bearing pads (CDP) offer a versatile and economical solution for bearing design. The CDPs have closely spaced layers of elastomer and ...
Strength and Stiffness of Circular Concrete-Filled Tubes
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled tubes (CFTs) are composite structural members that consist of a steel tube and concrete infill. CFTs optimize the contributions of both components by improving their geometric efficiency and fully using ...
Response and Modeling of Steel Tubes Filled with Recycled Fine and Coarse Aggregate Concretes under Long-Term Loading
Publisher: ASCE
Abstract: The engineering properties of concrete with recycled aggregates (RAC) can vary more widely than normal aggregate concretes (NAC). Because concrete-filled steel tubes do not rely solely on the concrete in compression, using ...
Strength of Circular Concrete-Filled Tubes with and without Internal Reinforcement under Combined Loading
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled tubes (CFTs) have been used in civil engineering practice as piles, caissons, columns, and bridge piers. Relative to conventional structural steel and reinforced concrete components, CFTs have several ...
Circular Concrete-Filled Tubes for Improved Sustainability and Seismic Resilience
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled tubes (CFTs) provide an opportunity for more sustainable structural systems through the use of concretes with high volumes of supplementary cementitious materials (SCMs) to replace cement. However, there ...
Improved Seismic Performance of Gusset Plate Connections
Publisher: American Society of Civil Engineers
Abstract: Current design practices use a strength-based design approach to design gusset plate connections in special concentrically braced frames (SCBFs), in which the expected tensile and compressive capacities of the brace are ...
Seismic CFST Column-to-Precast Cap Beam Connections for Accelerated Bridge Construction
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled steel tubes (CFSTs) frequently are a more efficient and economical structural solution then conventional reinforced concrete and structural steel. For the same size member, CFSTs offer increased strength ...
Rapid Assessment of Gusset Plate Safety in Steel Truss Bridges
Publisher: American Society of Civil Engineers
Abstract: Research into the cause of the failure of the I-35W Bridge in Minneapolis, Minnesota, has indicated that some of the gusset plates were significantly overstressed. The Federal Highway Administration has recommended load ...
