Scope

Scope: This document specifies the calculation methods, construction requirements, protection design, and inspection requirements for the design of embedded anchor bolts in oil and chemical industry installations using the failure mode-based method. This document applies to the design and inspection of embedded anchor bolts in oil and chemical industry installations, buildings, and equipment foundations. The anchor bolt design methods specified in this document are not applicable to the design of anchor bolts under fatigue or impact loads, nor to the design of anchor bolts with a nominal diameter greater than 100 mm. Main Technical Content: 5.1 General Provisions 5.1.1 The engineering design of anchor bolts shall include the following: a) Selection of anchor bolt types; b) Material selection; c) Determination of loads and load effects; d) Preliminary estimation and layout of anchor bolt diameters; e) Verification of the anchor bolt's limit state; f) Final selection of anchor bolt diameters, layout, and structural requirements; g) Requirements for fabrication, installation, and protection; h) Special design for meeting specific requirements. 5.1.2 The safety level and design service life of anchor bolts shall be the same as those of the connected components. 5.1.3 The design of anchor bolts shall adopt the limit state design method based on probability theory, and calculations shall be performed using the partial safety factor design expression. 5.1.4 The anchor bolts shall be designed for their bearing capacity limit state. The bearing capacity limit state of anchor bolts includes the failure of the anchor bolt steel, the failure of the base concrete, and the failure of the anchoring reinforcement. 5.1.5 Anchor bolts subjected to sustained tensile or shear forces shall be designed for their normal use limit state. When the connected component's design specifies clear requirements for the allowable deformation limit of anchor bolts,
