RISParametric Analysis of Three-dimensional Coupling Vibration for Hangzhou Bay Bridge
Publisher: American Society of Civil Engineers
Abstract: Coupling vehicle bridge vibration system were treated as two subsystems, one for the bridge and the other for the vehicle, the geometric and mechanical coupling relations between vehicle and bridge were introduced, the ...
Research on Internal and External Tendon System of Composite Box Girder Bridge with Corrugated Steel Webs
Publisher: American Society of Civil Engineers
Abstract: A 3D finite element model of an internal and external tendon concrete simple-supported composite box girder bridge with corrugated steel webs was established by means of the composite element method. The mechanical behaviors ...
Evaluation of Visual Comfort on Long-Span Suspension Bridges Experiencing Vortex-Induced Vibrations: Basic Framework and a Case Study
Publisher: American Society of Civil Engineers
Abstract: Vortex-induced vibration is a prevalent form of wind-induced vibration during the operation period of long-span suspension bridges. It significantly influences the comfort of drivers and passengers and reduces the bridge’s ...
Lateral-Torsional Buckling of Circular Steel Arches under Arbitrary Radial Concentrated Load
Publisher: American Society of Civil Engineers
Abstract: Steel arches are applied in many engineering structures because of their excellent capacity to resist various transverse loadings. Modified (or normalized) slenderness plays an important role in the strength design of steel ...
Nonlinear Dynamic Buckling of Fixed Shallow Arches under an Arbitrary Step Radial Point Load
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the nonlinear elastic in-plane dynamic buckling of a fixed shallow circular arch that was subjected to an arbitrarily located step radial point load, which has not been previously reported in the ...
Out-Plane Elastic-Plastic Buckling Strength of High-Strength Steel Arches
Publisher: American Society of Civil Engineers
Abstract: Little research has been reported for the out-plane elastic-plastic buckling strength of high-strength steel (HSS) arches and no adequate code provisions are available for their strength design, despite HSS structures being ...
Cost Constitution and Parameter Analysis of Bridge Engineering Computation Period by Considering Concerns of Decision Makers
Publisher: American Society of Civil Engineers
Abstract: This study discusses the objectives of state-level and enterprise-level positions of decision makers in bridge engineering decision problems and their hierarchical structures. Based on the aforementioned factors, cost ...
Lateral-Torsional Buckling of Shear Deformable Monosymmetric Steel I-Section Arches with Elastic Rotational-End Restraints under a Central Concentrated Load
Publisher: ASCE
Abstract: This paper investigates the elastic lateral-torsional buckling of shear deformable circular arches of monosymmetric steel I-section with in-plane elastic rotational end constraints under a central concentrated radial load. ...
Seismic Performance of Reinforced Concrete Bridge Columns Subjected to Combined Stresses of Compression, Bending, Shear, and Torsion
Publisher: American Society of Civil Engineers
Abstract: To explore the seismic performance of RC bridge columns subjected to combined stresses of compression, bending, shear, and torsion, reversed cyclic tests with eight column specimens were performed in the laboratory. ...
