Hands-On Structural Engineering Experiences With The "Anex" Mini-Laboratory, Richard A. Behr, Colin Othniel Benjamin, Azam A. Mirza Dec 1992

Hands-On Structural Engineering Experiences With The "Anex" Mini-Laboratory, Richard A. Behr, Colin Othniel Benjamin, Azam A. Mirza

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The ANEX facility has been developed to allow nearly real-time comparisons of analysis results with experimental data gathered on small-scale structural models. ANEX has been used successfully for in-class demonstrations, student-designed experiments, and comprehensive design/build competitions in an introductory structural analysis course at the University of Missouri-Rolla. An expert system is now being developed to guide ANEX users and to act as a trouble-shooter and advisor in the event that analytical and experimental results do not correlate acceptably well. ANEX, using only simple, small-scale model structures, is able to enrich structural engineering instruction by introducing students to the sophisticated capabilities …

Effect Of Strain Rate On Material Properties Of Sheet Steels, M. Kassar, Wei-Wen Yu Jan 1992

Effect Of Strain Rate On Material Properties Of Sheet Steels, M. Kassar, Wei-Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The effect of strain rate on tensile and compressive mechanical properties of sheet steels is investigated experimentally and analytically. Three sheet steels are studied in both longitudinal and transverse directions under different strain rates and different amounts of prior cold stretching in order to determine the separate effects of strain rate and aging half of the cold-stretched coupons are tested in an average of two days after cold-stretching operation. The remaining half are tested to failure at least 30 days after cold-stretching operation The results show that the proportional limit yield strength and ultimate strength increase with increasing strain rate …


Effect Of Strain Rate On Cold-Formed Steel Stub Columns, M. Kassar, C. L. Pan, Wei-Wen Yu Jan 1992

Effect Of Strain Rate On Cold-Formed Steel Stub Columns, M. Kassar, C. L. Pan, Wei-Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The material properties of steel and the strength of steel members are affected by strain rate to investigate this characteristic for compression members 49 stub columns fabricated from 35XF sheet steel and 48 stub columns fabricated from 50XF sheet steel are studied experimentally and analytically under different strain rates The strain rate ranged from 10-5 to 0.1. in./in./sec (10-5 to 0.1 mm/mm/s). The material properties of 35XF and 50XF sheet steels developed from previous tests are used for the evaluation of the test data obtained from the member tests using specimens fabricated from the same sheet steel. The …


Asce Lrfd Method For Stainless Steel Structures, Shin Hua Lin, Wei-Wen Yu, Theodore V. Galambos Jan 1992

Asce Lrfd Method For Stainless Steel Structures, Shin Hua Lin, Wei-Wen Yu, Theodore V. Galambos

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In recent years, probability-based load-and-resistance-factor-design (LRFD) method has been successfully applied to the design of hot-rolled steel sections and cold-formed steel members in the United States and foreign countries. In order to develop the LRFD criteria for the design of cold-formed stainless steel structural members and connections, a research project was conducted at the University of Missouri-Rolla since 1986 under the sponsorship of the American Society of Civil Engineers (ASCE). This newly developed LRFD Specification with Commentary has been adopted by ASCE as a new standard in 1990. It supersedes the 1974 edition of the Specification for the Design of …

Instability And Collapse Behavior Of A Seismic Structure, Franklin Y. Cheng, Jeng Fuh Ger Jan 1991

Instability And Collapse Behavior Of A Seismic Structure, Franklin Y. Cheng, Jeng Fuh Ger

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The collapse behavior of a 22-story steel building during the September 19, 1985, Mexico earthquake is investigated by studying hysteretic behavior, ductility factors of individual structural components, and overall instability of the building. The hysteresis models for truss-type girders, bracing members, and box columns to be used in the inelastic analysis of this building are developed. A series of inelastic analyses have been performed for the building by using the multicomponent seismic input of actual Mexico City earthquake records. It was found that the structural response exceeds the original design ductility of this building because most girders in the building …


Uplift Capacity Of Z-Purlins, Roger A. Laboube Jan 1991

Uplift Capacity Of Z-Purlins, Roger A. Laboube

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Roof systems constructed using cold-formed steel components, i.e., Z-shaped purlins and interconnected roof panels, have become a very popular form of construction. This roof system is used extensively for single-story commercial and industrial buildings in the United States. The popularity of cold-formed steel members is due in part to their superior gravity load strength-to-weight ratio; however, because of their relatively light weight, a cold-formed member is very susceptible to wind uplift loading. The design specification in the United States for cold-formed steel construction does not provide a comprehensive analytical solution to the problem of wind uplift strength of a cold-formed …
