RISStructural Stress Determination at a Hot-Spot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress analysis by a finite element analysis program sometimes causes singularities in hot-spots. In a failure assessment, the structural stress, and membrane and bending stress should be determined in a highly stressed ...
Fatigue Evaluation of API 12F Shop-Welded Tanks With a New Roof-to-Shell Junction Detail
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The American Petroleum Institute (API) provides a series of standards and specifications on storage tanks, in which the API 12F specification provides 12 tank designs that can be fabricated in the shop and transported to ...
Determination of Failure Pressure Modes of the API Specification 12F Shop-Welded, Flat-Bottom Tanks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shop–welded, flat-bottom tanks for storage of production liquids are designed and fabricated in specific dimensions and capacities for internal pressures close to atmospheric pressure in accordance with the API 12F ...
Failure Modes of American Petroleum Institute 12F Tanks With a Rectangular Cleanout and Stepped Shell Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design and fabrication of shop-welded and prefabricated relatively small tanks, when compared to field-welded tanks, used in the upstream segment of the oil and gas industry is governed by the American Petroleum Institute ...
Failure Mode Determination of American Petroleum Institute 12F Shop-Welded Tanks With a New Roof-to-Shell Junction Detail
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The American Petroleum Institute (API) 12F is the specification for vertical, aboveground shop-welded storage tanks published by the API. The nominal capacity for the twelve tank designs given in the current 13th edition ...
Influence of Internal Inward Pressure on Stability of Open-Top Aboveground Steel Tanks Subjected to Wind Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The results of wind tunnel tests indicate that there is an internal inward pressure induced by wind excitation when open-top tanks are examined, but not when close-top tanks are examined. This internal pressure is considered ...
Influence of Internal Inward Pressure on Stability of Open-Top Aboveground Steel Tanks Subjected to Wind Loading
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The results of wind tunnel tests indicate that there is an internal inward pressure induced by wind excitation when open-top tanks are examined, but not when close-top tanks are examined. This internal pressure is considered ...
Stability of Open-Topped Storage Tanks With Top Stiffener and One Intermediate Stiffener Subject to Wind Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aboveground vertical steel storage tanks use stiffener rings to prevent their shell wall from buckling under wind loading. The existing stiffener rings design rules from API 650 standard is known to be overly conservative. ...
Seismic Analysis of Open-Top Storage Tanks With Flexible Foundation
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The behavior of aboveground storage tanks subjected to seismic excitation was investigated using numerical methods by taking flexibility of foundation into account. The hydrostatic load due to stored liquid has an axisymmetric ...
