STEEL DESIGN 15 Bolted Connections - Combined Stresses

WebThis general rule applies because the bolt is subjected to combined stress (tension and torque) during installation. Once installed, however, the torque is relaxed, and the bolt is essentially subject only to tensile stress that is always less than the combined stress. Thus, even if the bolt were on the verge of failure during installation, it ... certified apt staffing https://aweb2see.com
