RISAnalytical Study on Response Power Spectral Density of Structures Subjected to Nonstationary Excitation Considering Transient Responses
Publisher: ASCE
Abstract: Computing the response power spectral densities (PSDs) of structures from the excitation PSDs has always been a classical problem in structural random vibration. Conventional analytical methods ignore the frequency ...
Tropical Storm–Induced Buffeting Response of Long-Span Bridges: Enhanced Nonstationary Buffeting Force Model
Publisher: American Society of Civil Engineers
Design and Analysis of Concrete-Filled Rectangular Steel Tubular Truss-Arch Composite Bridge Stiffened with PBL
Publisher: ASCE
Abstract: Under the influence of long time load actions, shrinkage and creep of concrete, temperature variation, and concrete pouring quality, debonding may occur between steel tube and concrete. Debonding affects the mechanism ...
Hydromechanical Analysis of Collapse Settlement of Loess during Field Immersion Tests: Field Investigations and Numerical Modeling
Publisher: American Society of Civil Engineers
Abstract: Loess is the most well-known collapsible soil. The field immersion test is one of the effective means to assess the in situ self-weight collapsibility of soil. However, the reason why huge differences appeared in collapse ...
