International Journal of Concrete Structures and Materials, 2023 The seismic performance of a concrete column retrofitted with an iron-based shape memory alloy (Fe-SMA) was evaluated under cyclic loading. In addition to structural behavior, internal damage was monitored using an ultrasonic pulse velocity test.

Parametric studies on the ductility of axial loaded square reinforced concrete column made of normal-strength concrete (NSC) and high-strength steel confining rebar (HSSCR) with various ties configuration [PDF]
E3S Web of Conferences, 2020 During an earthquake, Reinforced Concrete (RC) building structures should behave in a ductile manner to prevent the structures from collapse. Therefore, the column element should have sufficient ductility to sustain an axial load at the post-peak region.

CONFINEMENT OF RC COLUMNS WITH CFRCM
Proceedings of International Structural Engineering and Construction, 2020 Textile reinforced concrete is becoming increasingly important in construction. Besides the application in new constructions, textile reinforcement can be used for the strengthening of plain and reinforced concrete structures in the form of fabric reinforced cementitious matrices (FRCMs).

Numerical Investigation of Behavior of RC Columns Strengtheneg with RC Jacket [PDF]
Academic Perspective Procedia, 2019 Strengthening of structural elements which are insufficient in terms of earthquake performance is very important for the safety of existing structures. Nowadays, one of the most commonly used methods is strengthening such members with RC jacketing. Several experimental studies have been conducted in the literature to investigate behavior of structural ...

Optimal Design of Seismic Resistant RC Columns [PDF]
Materials, 2020 Although the author is well aware that it is nothing special, presented here is the method that he uses to design the columns of a seismic resistant reinforced concrete structure, in hopes that this could be of use to someone. The method, which is directed at satisfying the capacity design requirements without excessively large sections, consists of ...
