Material Effects on Tangent Modulus of Steel Square Hollow Section by Seyed Mohammad Reza Mortazavi, Milad Shakiba, Behrouz Zaeimdar

“…The kind of mild steel, the Bauschinger effect because of strain reversal and strain ageing are indicated to affect significantly the tangent modulus of elasticity. Stub column specimens made from a material that has been pre-stretched in tension have a significantly lower tangent modulus of elasticity than those specimens made from as-received material; the reduction is caused by the Bauschinger effect and a resulting reduction in tangent modulus and yield strength. …”

Identifikasi Penyebab Kerusakan Konstruksi Bangunan Beton Bertulang Pasca Bencana Gempa Bumi by Jafril Tanjung, Nilda Tri Putri

“…Non-standard reinforcement detailing includes a lack of the required amount of reinforcement in the structure, installation of shear reinforcement that does not meet the requirements, and a lack of shear reinforcement at beam and column connections. Lack of reinforcement in structural connections reduces the strength and stiffness of the structural system, thereby increasing the risk of collapse during an earthquake. …”
