Safety Margins of Suspension Bridges Under Seismic Conditions
Publisher: American Society of Civil Engineers
Abstract: The American Association of State Highway Transportation Officials (AASHTO) 1983 code, “Seismic Design of Highway Bridges,” does not cover explicitly suspension bridges. Nevertheless, if AASHTO earthquake excitation is ...
Concrete Toughness after 20 Years
Publisher: American Society of Civil Engineers
Abstract: Test results are presented showing stress‐strain diagrams of aged and young plain concrete columns
Lateral Vibration of Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: Besides the pendulum action developed by the suspended deck, the restoring force exerted by a cable during lateral displacements is expressed by the horizontal component of the cable tension, times the curvature of the ...
Reinforced Concrete Columns under Cyclic Axial Compressive Forces
Publisher: American Society of Civil Engineers
Abstract: The stress‐strain diagram of a short concrete specimen under compressive uniaxial load cycles is enveloped by a curve that matches the stress‐strain curve obtained under constantly increasing strain. At least eight published ...
Large Amplitude Oscillatory Shear From Viscoelastic Model With Stress Relaxation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analytic response for the Cauchy extra stress in large amplitude oscillatory shear (LAOS) is computed from a constitutive model for isotropic incompressible materials, including viscoelastic contributions, and relaxation ...
