RISSimplified Dual Nonlinear Analysis Method of CFST Laced Structures
Publisher: American Society of Civil Engineers
Abstract: Based on continuous assumption, laced CFST member can be simplified as a beam element. Stiffness of Timoshenko beam was adopted to calculate the equivalent solid member stiffness matrix of the laced structure, in which the ...
Assessments of Water Sorption Methods to Determine Soil’s Specific Surface Area
Publisher: ASCE
Abstract: A soil’s specific surface area (SSA) is commonly determined by two conventional methods: adsorption isotherms using nitrogen gas with interpretation through the Brunauer-Emmet-Teller (BET) equation, and ethylene glycol ...
Studies of In-Plane Ultimate Loads of the Steel Truss Web–RC Composite Arch
Publisher: American Society of Civil Engineers
Abstract: This paper describes an experiment on the in-plane mechanical behaviors of the steel truss web–RC composite arch subjected to the unsymmetrical concentrated loads applied simultaneously at the
Overview of Concrete Filled Steel Tube Arch Bridges in China
Publisher: American Society of Civil Engineers
Abstract: This paper briefly introduces the present situation of concrete filled steel tube (CFST) arch bridges in China. More than 200 CFST arch bridges were investigated and analyzed based on the factors of type, span, erection ...
Correlation between Atterberg Limits and Soil Adsorptive Water
Publisher: ASCE
Abstract: The Atterberg limits are empirical indices of the critical water contents defining mechanical states of soil-water mixtures between the semisolid state and plastic state (the plastic limit or wP), and between the plastic ...
Water Adsorption–Induced Pore-Water Pressure in Soil
Publisher: ASCE
Abstract: Pore-water pressure in soil is caused by three physically distinguishable sources: ambient (environmental) pressure, surface tension–induced capillary pressure, and the soil’s electromagnetic potential–induced adsorptive ...
Rehabilitation and Retrofitting of a Multispan Simply-Supported Adjacent Box Girder Bridge into a Jointless and Continuous Structure
Publisher: American Society of Civil Engineers
Abstract: The widely-utilized multispan simply-supported adjacent (side-by-side) box girder bridges often suffer from problems of deterioration attributable to transverse cracking in link slabs between spans, malfunctioning expansion ...
Equivalent Beam-Column Method to Estimate In-Plane Critical Loads of Parabolic Fixed Steel Arches
Publisher: American Society of Civil Engineers
Abstract: The objective of this paper is to investigate the characteristics of critical loads for parabolic fixed steel tubular arches. An advanced nonlinearity finite-element program, taking into account the geometric and material ...
Dynamic Effect of Tie-Bar Failure on Through Tied Arch Bridge
Publisher: ASCE
Abstract: Tie bars on through tied arch bridges are often in poor condition and may serve as an external cause of a tie-bar failure accident; nevertheless, bridge structural robustness contributes greatly in resisting progressive ...
Robustness Assessment Framework for Through Tied-Arch Bridge Considering Tie-Bar Failure
Publisher: ASCE
Abstract: Compared with those of other bridge types, the structural system of through tied-arch bridges is particularly susceptible to failure owing to the deterioration and fracturing of tie-bars as well as a lack of structural ...
