Load And Resistance Factor Design Of Cold-Formed Stainless Steel Statistical Analysis Of Material Properties And Development Of The Lrfd Provisions, Shin-Hua Lin, Wei-Wen Yu, Theodore V. Galambos

CCFSS Library (1939 - present)

INTRODUCTION 1.1 General Remarks The "Allowable Stress Design" method has long been used for the design of steel structures in the United States. 1,2,3 Recently, the probability-based load and resistance factor design (LRFD) criteria have been successfully applied to the structural design of hot-rolled steel shapes and built-up members. 4,5,6 The AISI LRFD Specification is being developed as well for the design of structural members cold-formed from carbon and low alloy steels. 7-17 These design criteria can provide a more uniform degree of structural safety to achieve consistent reliability for different design situations. The probability-based design method is developed on …

Design Of Automotive Structural Components Using High Strength Sheet Steels Structural Strength Of Cold-Formed Steel I-Beams And Hat Sections Subjected To Web Crippling Load, Shin-Hua Lin, Ling-En Hsiao, Chi-Ling Pan, Wei-Wen Yu

CCFSS Library (1939 - present)

INTRODUCTION When cold-formed steel beam webs are subjected to partial edge loading, they may fail by web crippling rather than bending of the beam. Web crippling is caused by a highly localized intensity of the load or reaction. Because of the complexity of the web crippling behavior, empirical expressions are presently used for the design of cold-formed steel beams in buildings and automotive structural components to prevent web crippling. 1,2,3. The research on the structural behavior of cold-formed steel beam webs subjected to web crippling has been conducted at Cornell University and the University of Missouri-Rolla (UMR) under the sponsorship …

Load And Resistance Factor Design Of Cold-Formed Steel: Calibration Of The Aisi Design Provisions, Wei-Wen Yu, Ling-En Hsiao, Theodore V. Galambos

CCFSS Library (1939 - present)

In the design of steel buildings, the "Allowable Stress Criteria" have long been used for the design of cold-formed steel structural members in the United States and other countries.' In view of the fact that the mathematical theory of probability, which has been so successfully applied in other fields of engineering, would seem to be equally applicable to cold-formed steel design by providing a more uniform degree of structural safety, the "Limit State Design" method based on the probabilistic concept has been used in Canada and Europe for the design of cold-formed steel structural members.' In the United States, a …

Load And Resistance Factor Design Of Cold-Formed Steel Comparative Study Of Design Methods For Cold-Formed Steel, Ling-En Hsiao, Wei-Wen Yu, Theodore V. Galambos

CCFSS Library (1939 - present)

Allowable Stress Design is the current method used to design cold-formed steel structural members and connections. In this design approach, factors of safety are used to compute the allowable design stresses which are compared to the actual maximum stresses that will occur in the member during the life of the structure. In recent years, the Load and Resistance Factor Design (LRFD) method has been developed for the design of hot-rolled steel shapes and the design of cold-formed steel structural members. This method is based on probabilistic and statistical techniques to account for the many uncertainties involved with the actual design. …

Technical Report El-88-18: Reliability Of The Federally Owned Water Main System, Donald V. Chase, Lindell Ormsbee, Thomas M. Walski

Civil and Environmental Engineering and Engineering Mechanics Faculty Publications

The reliability of the Federally Owned Water Main (FOWM) system was examined, and recommendations to improve system reliability are made. The existing FOWM system is very dependent upon three different pipe links.

The first and most important link is the Francis Scott Key Bridge river crossing. This link carries the entire FOWM supply, and if taken out of service, an alternate means of supply must be used. At present, the only alternate source of supply is through interconnections with the adjacent Arlington County, Virginia, system.

The second vital link is the 30-in. steel main which extends from the Key Bridge …

Computer-Aided Analysis And Design Of Rectangular Buried Tank Walls And Its Safety Factor Evaluation Based On Yield Line Analysis, Rakiya J. Fatoohi

Civil & Environmental Engineering Theses & Dissertations

This thesis presents the results of a study that determines the true safety factor of underground square reinforced concrete tank walls.

The walls are analyzed and designed by elastic method. The amount and distribution of the reinforcement was determined by use of the alternate design method (working stress) in compliance with all ACI code requirements. The wall's ultimate moment was computed by use of yield line theory assuming non-isotropic reinforcement. The ultimate value of the earth pressure was computed and compared with the elastic analysis and design values to give the true safety factor.

The results of this study indicate …

Structural Sensitivity Analysis On A Parallel Computer, Niu Kian Teck

Civil & Environmental Engineering Theses & Dissertations

Substructuring formulation using adjoint variable approach has been developed for design sensitivity analysis and optimization of large scale structures. In this study, the procedure for statics and sensitivity analysis are re-examined to propose a programming scheme which can be implemented either in a sequential or parallel environment. The computational times of the substructuring formulation using a single processor versus multi-processors are compared to see the effectiveness of the formulation in the concurrent computing environment.

Expanding The Automated Centralized Control System At The Des Moines Area Community College, Mark David Baethke

Graduate Research Papers

DMACC currently has over $1,200,000 invested in the ACCS which is connected to 21 campus buildings. The ACCS is used to save an estimated $300,000 per year in energy costs through energy conserving control of heating, ventilating, and air conditioning equipment. The ACCS also improves building life safety functions through fire alarm monitoring and serves as a significant trouble shooting tool for the mechanical maintenance staff. The initial installations of the ACCS were done after lengthly audits and studies by professional consulting firms which resulted in the recommendations for installation and expansion. These studies were limited to only a few …

Design Of Automotive Structural Components Using High Strength Sheet Steels Structural Behavior Of Members Consisting Of Flat And Curved Elements, M. Brad Parks, Wei-Wen Yu

CCFSS Library (1939 - present)

Local buckling of stiffened and unstiffened curved elements has been investigated both experimentally and analytically. Stiffened curved elements are supported along both longitudinal edges while unstiffened curved elements are supported along one longitudinal edge with the other longitudinal edge free. A series of stub column, beam, and shear tests have been performed for sections containing curved elements. The tested specimens were formed from sheet steels with yield strengths ranging from 27 to 88 ksi. The radius-to-thickness, R/t, values of the curved elements varied from 12 to 438 whereas the arc length-to-thickness, b/t, ratios ranged from 23 to 218. As a …
