Its more accurate method to analyze the eccentric connections but it requires lot of iteration.

MAXIMUM & MINIMUM NUMBER OF ONE ROW OF BOLTS FOR W-SECTIONS (AS PER AISC)ĭesign Checks for Bolts (As per AISC Manual 15 th edition )įor slip critical connection, Refer Section J3.8 This extension will twist off when torque to the required tension by special torque gun. The alternative design bolt (twist off or TC bolts) is a bolt with extension to the actual length of the bolts. When the bolts torqued, the dimples depress to the manufacture’s specification requirements, and proper torque can be measured using feeler gage. The direct tension indicator (DTI) hardened steel load indicator washer has dimples on the surface of one face of the washer.
ASTM-A490 (Structural bolts)-Fully tensioned & snug tight-70% of tensile strength of bolt.ASTM-A325 (Structural Bolts)-Fully tensioned & snug tight-70% of tensile strength of bolt.They consist of fasteners that capture and join other parts, and are secured with the mating of screw threads.Īs per AISC We have 3 type of bolts which are commonly used Bolts are one of the most common elements in construction and machine design.
