Axial Behaviour of Slender RC Circular Columns Strengthened with Circular CFST Jackets

Theoretical model for slender FRP-confined circular RC columns

An important application of fiber-reinforced polymer (FRP) composites is to provide confinement to reinforced concrete (RC) columns to enhance their loadcarrying capacity. However, this application is generally restricted to short columns as existing design guidelines do not contain provisions for the design of FRP jackets for slender columns. This situation has been due to both the scarcity of...

Post-buckling behaviour of a slender beam in a circular tube, under axial load

This paper deals with the study of the behaviour of a slender beam introduced in a cylindrical tube and subjected to an axial compressive force. The beam is very long compared to its transversal dimensions and therefore it will buckle to a very small axial force. The post-buckling behaviour is examined. The study has important applications in the petroleum industry, for coiled tubing in the cas...

ارزیابی و مقایسه‌ی رفتار ستون‌های بتن مسلح دایره‌ای و مربعی تقویت ‌شده با جاکت‌های فولادی در برابر انفجار

Evaluation and Comparison of Behavior of Steel Jacketed RC Columns with Circular and Square Sections under Blast Loading Reinforced concrete (RC) structures are widely used in urban buildings and infrastructures, and these are always subjected to explosions caused by intentional or unintentional accidents. Among the structural members, columns are key load carrier elements. In this paper, b...

Behaviour of FRP wrapped circular concrete columns under eccentric loading

Investigation of vortex-induced vibration phenomenon in verticallong circular slender structure with non-uniform flows

Analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. This slender is free to move in both in-line and cross flow directions and immersed completely in water. Three different types of shear currents pass on it and cause to vibrate slender in different forms. Nowadays, these vibrations are very important for de...
