Engineering Seismology Aspects Of The M-6.5, Southern Italy Earthquake Of Nov. 23, 1980: A Preliminary Review, E. Faccioli

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

The paper provides an overview of salient engineering seismology features of the earthquake, which was one of the major seismic catastrophes occurring in Italy in this century. After a short description of the characteristics of the earthquake source and of the historical seismicity of the region, preliminary strong-motion and intensity data are presented. Aspects of geotechnical engineering interest include some large landslides in inhabited areas, and notable cases of correlation between severity of damage and local soil conditions and topography.

Attenuation Of Ground Vibration Induced By Dynamical Machinery, S. J. Yang

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

Attenuation of ground vibration induced by dynamic machinery is investigated with fundamental theory established for both Rayleigh and body waves. Therefore, for determining such attenuation is established, in which the effects of both of them and a coefficient of attenuation of soil that makes the practical calculation easier are involved. A lot of data in relation to the surface vibration measured at some production shops and construction sites has proved that the developed formula more satisfactory than Bornitz's.

Considerations About Some Aspects Of The 23rd November 1980 Earthquake, Filippo Ciuffi, Giuseppe Samela

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

The macroscopic effects of the earthquake of the 23rd of November 1980 in southern Italy are well-known. The purpose of this short paper is to present after about five months, some more exact testimonies with some considerations about numerous questions connected to the geotechnical and geological problems in seismic areas. We have to be precise that we, in this paper, contemplate the MURO LUCANO and CASTELGRANDE areas (in Basilicata) (fig. 1)

On Surface Waves In A Gibson Half-Space, I. Vardoulakis, V. Dougalis

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

Harmonic Rayleigh-type and transverse surface waves in a half-space of incompressible material with constant density and with shear modulus linearly increasing with depth (Gibson half-space) are discussed. Under certain hypotheses a discrete spectrum yielding polynomial Eigen functions is obtained, a fact which makes the eigenvalue problem more tractable. The dispersion laws are presented and evaluated numerically.

Web Crippling And Combined Web Crippling And Bending Of Steel Decks, Wei-Wen Yu

CCFSS Library (1939 - present)

INTRODUCTION A. General During the period of October 1968 through September 1980, the 1968 Edition of the AISI Specification was used for the design of steel deck webs that could withstand web crippling and combined web crippling and bending. (1) The design formulas used to prevent web crippling were developed primarily on the basis of tests conducted in the 1940's and 1950's at Cornell University. (2-4) Recently, new types of cold-formed steel sections have been developed and used in building construction. The use of unusual geometric configurations has complicated the design of such members. In order to develop new design …

Behavior Of C- And Z-Purlins Under Wind Uplift, Parviz Soroushian, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION Cold-formed steel lipped channel (C-) and Z-purlins are used widely in the roofs of metal buildings. They are easy and economical to fabricate and erect. However these sections are weak in the lateral direction and in torsion. In order to use their full bending capacity in the strong direction, they must be braced in the lateral direction and against twisting. Roof panels which are connected to the purlins do provide to some extent such bracing effect by virtue of their shear rigidity and resistance to local bending at the connections. Wind uplift is an important design condition for roof …

Steel Deck Institute Diaphragm Design Manual First Edition, Larry D. Luttrell

Steel Deck Institute (SDI) Specifications and Manuals (1939 - present)

The Major Units Laboratory at West Virginia University has been involved in full-scale diaphragm studies for the past fifteen years. The work has covered tests on a wide range of deck panel types, metal building wall systems, panels with insulating concrete fill, and plywood assemblies, all used as diaphragms, and under static, cyclic, and dynamic loading. Connection performance, critical to diaphragm behavior, has been evaluated through an extensive test program covering arc-spot (puddle) welds, different types of screws, and power driven pins. These have established fastener strength limits and have been especially important for defining fastener flexibility factors.

Fire Protection Through Modern Day Building Codes, D. F. Boring, James C. Spence, Walter G. Wells

CCFSS Library (1939 - present)

In this edition, fire protection regulations are not included and requirements of model codes and recommendations of code writing organizations are cited in the text. Much progress has been made in building construction techniques and in material development since the publication of the First Edition in 1944. While this Fifth Edition reflects that progress, it adheres to its original purpose to help develop construction standards for safeguarding life and property from fire.

Phase 1 Inspection Report: National Dam Safety Program. Upper Mississippi - Kaskaskia - St. Louis Basin. Lake Bono Del Dam, Jefferson County, Missouri, Horner & Shifrin, Inc., St. Louis, Missouri

Missouri Dam Safety Inspection Reports

This report presents the results of field inspection and evaluation of the Lake Bono Del Dam (MO 30434):

It was prepared under the National Program of Inspection of Non-Federal Dams.

This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria:

1) Spillway will not pass 50 percent of the Probable Maximum Flood without overtopping the dam.

2) Overtopping of the dam could result in failure of the dam.

3) Dam failure significantly increases the hazard to loss of life downstream.

Transverse Thermal Response Of A Composite Bridge, Michael J. Filla

Masters Theses

"A two-span, composite-design, test structure was subjected to thermal loading. The resultant longitudinal and transverse response was correlated with that calculated by a prior theoretical procedure. The theoretical procedure was reconfirmed for longitudinal stress, and indicated within reasonable probability for transverse stress. No measurable diaphragm influence was observed"--Abstract, page iii.

Load And Resistance Factor Design Of Cold-Formed Steel Structural Members, Boonsong Supornsilaphachai

Doctoral Dissertations

"In a traditional design, the Allowable Stress method has long been used for the design of cold-formed steel structures. In this design approach, the allowable stress is always used to prevent the possible structural failure by using an appropriate factor of safety selected primarily on the basis of engineering judgment and long-time experience.

Recently, the concepts of risk and reliability analysis have been successfully applied to many fields of engineering. By applying the theories of probability and statistics, the load and resistance design criteria for steel structures have been developed for the design of hot-rolled steel shapes and built-up members. …
