An Exploratory Study On The Behavior Of Cold-Formed Steel Wall Studs, Yaochun Zhang, Teoman Peköz

CCFSS Library (1939 - present)

GENERAL Cold-formed steel wall studs are widely used in the U. S. and Canada. The 1980 A.I.S.I Specification (Ref. 1) contains provisions for the design of such wall studs based primarily on the research conducted at Cornell University (Refs. 2 and 3). This research involved theoretical and experimental studies on wall studs subjected axial loads only. The Specification provisions on the case of combined axial and lateral loading were derived intuitively and were made intentionally conservative. The excessive conservatism in the provisions for the combined loading case prevents using wall studs as economically as possible. The primary objective of the …

Seismic Design For Buildings, Department Of The Army, The Navy, And The Air Force

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

This updated manual with revised seismic design provisions governs the design and construction of Army, Navy, and Air Force facilities and supersedes the April 1973 issue. Basic criteria are stated herein with augmentations and clarifications of the criteria. Also, commentary and design examples are included to provide comprehensive applications and guidelines for the seismic-resistant design of facilities. The organization of the manual has been revised to present the topics in a more orderly manner. The dynamic analysis approach for seismic design is not covered but its use is not precluded in this manual.

The basic criteria cited are the "Recommended …

Geotechnical Evaluation Of The Support Of Coal Pillars In Underground Coal Mines., John D. Rockaway, Richard W. Stephenson

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Study Described Was Accomplished through an Investigation of Both the Intact and Insitu Geotechnical Properties of the Sub coal Strata and through the Installation of Floor Movement Monitoring Instrumentation. the Method of Bearing Capacity Analysis Developed by A. S. Vesic Was Used to Define Pillar Stability. This Method Includes Provisions for Taking into Consideration a Two-Layer System Such as Assumed for Mine Conditions Where a Weak Underclay overlies Firmer Strata.

A New Soil Model And Dynamic Soil Properties, Y. Gyoten, K. Mizuhata, T. Fukusumi, H. Hamada, T. Hirose

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

A series of cyclic triaxial loading tests with varying strain amplitude were performed on samples of clay and sand. Three types of polynomial functions and a hyperbolic function were applied to express the experimental nonlinear hysteresis curve of soils under cyclic loading conditions. These functions were used for the earthquake response analysis of the actual ground containing alluvial clay layer and of the idealized saturated sandy soil ground whose stiffness gradually decreases as the development of pore-water pressure. The results of the dynamic responses and the liquefaction potential were compared for a particular actual site and an idealized site by …

Creep Effects On Low-Amplitude Modulus Of Clays, G. A. Athanasopoulos, F. E. Richart Jr.

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

The investigation considered effects of on-going or previous drained creep on the low amplitude dynamic shear modulus of normally consolidated artificial and natural clay soils. Resonant column tests using the Hardin and Hall devices determined the low-amplitude shear modulus. Results indicated that the strain-rate of on-going creep determined the kind of effect on shear modulus. High strain-rates produced reduced values whereas low strain-rates slightly increased values of modulus, compared to the no-creep values. Previous creep produced higher values of modulus, when the clay was tested under after-creep isotropic confinement. The rate of secondary increase of shear modulus was not affected …

The Shear Modulus And Deformation Of Soils Under Cyclic Loading, Ting Hu

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

In this paper the dynamic deformation stages of soils under cyclic loading and the major factors affecting the shear modulus of soils are analyzed. The in-situ measurement of surface wave by larger energy source to obtain the shear modulus of the ground is described. On considering the important effect of shearing dilatancy on shear modulus of sandy soils, a modified formula is proposed. For typical soils, the axial strains under cyclic loading are determined either for estimating shear modulus or for the deformation analysis in design.

In Situ Measurement On Dynamic Modulus And Damping Of Pleistocene Soils, H. Mori, H. Tsuchiya

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

The paper presents the results of measurement on the dynamic modulus of deformation and damping ratio of dense sand or stiff clay of the Pleistocene epoch using a dynamic pressuremeter. The paper first describes an outline of an instrument and procedures of the dynamic pressuremeter test, which include necessary correction of data for eliminating the influence of compressibility and damping of the instrument. From the results of field measurement, the moduli derived from the dynamic pressuremeter tests were found several times greater than those from laboratory tests which were affected by disturbance of soil samples.

Dynamic Triaxial And Vibratory In-Situ Behavior Of Cohesive Soil, M. S. Ei-Hosri, J. Biarez, P. Y. Hicher

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

In-situ and laboratory shear modulus data are presented and compared. In-situ tests included the cross-hole seismic survey at a stiff marl site, while laboratory tests included the cyclic triaxial test on undisturbed specimens obtained from the same site. The cyclic triaxial device presented in this investigation has been developed and improved so that the reliable response of soil can be measured directly from the specimen over a large range of strain (from 10^-6 to 10^-2 ). A series of cyclic triaxial tests were performed under stress controlled condition over a range of frequency from 0,5 to 10 Hz …

Dynamic Behavior Of Soils From Field And Laboratory Tests, W. P. Grant, F. R. Brown Jr.

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics

Both geophysical and laboratory tests were used to determine the dynamic shear moduli of medium stiff to hard clays and silts at six sites. The geophysical measurements included conventional downhole tests conducted at low strain levels and modified cross-hole impulse tests conducted over a wide range of strains. Laboratory resonant column and cyclic triaxial tests were performed on soil samples retrieved from borings made at the sites. The results from both the field and laboratory tests of the medium stiff to stiff sols showed fairly good agreement. The laboratory test results of the hard clays and silts, however, were typically …
