RISNonstationary Response Envelope Probability Densities of Nonlinear Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonstationary random response of a class of lightly damped nonlinear oscillators subjected to Gaussian white noise is considered. An approximate analytical method for determining the response ...
A Method for Fatigue Analysis of Piping Systems on Topsides of FPSO Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipelines located on the decks of FPSO systems are exposed to damage due to sea wave induced random loading. In this context, a methodology for estimating the fatigue life of fluid-conveying ...
New Confined Concrete Stress–Strain Model for Square Double-Skin FRP-Concrete-Steel Stiffened Tubular Columns
Publisher: American Society of Civil Engineers
Abstract: Double-skin tubular columns (DSTCs) are promising modern columns with concrete sandwiched between fiber-reinforced polymer (FRP) and steel skins. Typical concentrated and localized failure modes in DSTCs can be constrained ...
Tests on Short Outer Tube–Stiffened CFDST Columns: Effect of Stiffener Distribution on Axial Performance
Publisher: American Society of Civil Engineers
Abstract: Previous studies on concrete-filled double-skin tubular columns (CFDSTCs) have demonstrated a superior axial performance when outer steel tubes are reinforced with steel stiffeners. As a result, recommendations for stiffener ...
