Wind Loads and Anchor Bolt Design for Petrochemical Facilities

These committee reports provide state-of-the-practice guidelines for the determination of wind induced forces and the design of headed, cast-in-place anchor bolts for petrochemical facilities. The basis and procedures for determining wind induced forces for enclosed structures and other conventional structures are addressed, in addition to load components such as force coefficients, tributary areas, and shielding for industrial-type structures and equipment. Topics include comparisons of current design practices, recommended guidelines, examples, and research needs of pipe racks, open frame structures, and pressure vessels. The second report evaluates current petrochemical industry anchor bolt design methods, proposed changes and new releases of design codes, and provides recommendations that supplement current codes for design of headed, cast-in-place anchor bolts. Subject areas include the current state of research, grades, fabrication and welding, corrosion, bolt configuration and dimensions, distribution of anchor bolt forces, checking critical modes of failure, pier design/reinforcing, pretensioning, and considerations for vibratory and seismic loads.
