Prevention of torsional irregularity in steel structures via brace members

open access: yes, 2022
Steel structures can be designed using moment-resisting frame systems or braced framesystems. Torsional irregularities can occur in non-symmetrical structures designed withmoment-resisting steel frame systems.

An experimental and numerical investigation on the effect of longitudinal reinforcements in torsional resistance of RC beams

open access: yes, 2013
It is evident that torsional resistance of a reinforced concrete (RC) member is attributed to both concrete and steel reinforcement. However, recent structural design codes neglect the contribution of concrete because of cracking.

Behaviour and Design of Unstiffened Wide-Flange Members Subjected to Torsional Moment through One Flange [PDF]

open access: yes, 2016
Behaviour of the unstiffened wide flanged member is not characterized by the available literature or current design standards. Torsional moment applied on the one flange unstiffened member causes the member to undergo local distortions.

Bracing FRP I-section beams to avoid lateral-torsional buckling

open access: yes, 2011
This article explains as to how lateral-torsional buckling can be avoided in fiber-reinforced plastic (FRP) beams having an I-shaped cross section and subjected to major-axis bending. To enable a FRP beam to be able to develop its maximum bending moment
