A Generic Inflatable Structure for a Lunar/Martian Base
The first steps in the human expansion into space, which inevitably will occur during the next century, consist of the establishment of a human-tended base on the Moon followed by human...
Preserve and Protect
Historic and landmark structures constructed of unreinforced masonry and stone are among the most vulnerable to strong ground shaking and are often subject to possible collapse. For the...
Safety Assessment of a Chemical Reactor Vessel
The potential explosion loadings on a chemical reactor vessel is described in this paper. The potential loads presented provide a basis for designing spherical storage vessels which will...
The Inelastic Response of an Offshore Platform in Hurricane Andrew
Amoco's Gulf of Mexico South Timbalier 161A platform took a direct hit from Hurricane Andrew in August of 1992, experiencing loads which far exceeded its design load. The platform had...
Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
Nonlinear Collapse of Offshore Jacket Structures
The Joint Industry Tubular Frames Project was established with ten oil industry sponsors to investigate the reserve and residual strength of frames typical of offshore structures. To date...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...
Load Duration Effects in an 85-Year-Old Timber Structure
Duration of load (DOL) effects are assessed in 85-year-old heavy timber trusses using five common DOL models. These models are based on the idea of static damage accumulation. Material...
Seismic Analysis of Bridges: Simplified or Refined Approach
This paper discusses the differences of seismic responses of bridges among various analysis methods and approaches....
Dynamic Loading of a Rigid Frame Bridge
The objective of this paper is to investigate the dynamic response of a rigid frame bridge to two trucks (side by side) passing over the rough bridge deck. The rigid frame bridge is designed...
Bridge Rail Impact Forcing Functions
Bridge rails are designed according to AASHTO standards with a static 10-kip (44.5 kN) lateral load. The computer programs BARRIER VII and COSMOS are used to determine the deflections...
U.S. / Japan Large Scale Cooperative Research Program for Steel Structures
The US/Japan Cooperative Research Program Utilizing Large Scale Test Facilities for Earthquake Resistant Design was initiated in 1980 using a combination of full-scale, small-scale, subassemblage...
Impediments to the Implementation of Seismic Isolation
There are over 400 civil engineering structures, worldwide, that have been constructed using the principles of seismic isolation, and 70 of these are in the United States. Although use...
First Bank Place: A Composite Cruciform Spine
The First Bank Place, designed by the internationally known architectural firm of Pei Cobb Freed and Partners, is a granite-clad, 56 stories tall building in downtown Minneapolis. Presented...
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
Application of Concrete-Filled Steel Tubular Columns in Tall Buildings in Earthquake Area
In this paper an outline is given of the background, the design concept, structural features, construction and economy of the concrete-filled steel tubular coumns of tall buildings in...
Recent Developments in Seismic Response of Composite Structures
Lack of sufficient data has limited a wider application of structures using mixed steel-concrete construction in seismically active regions. This paper summarizes some recent studies at...
Talmadge Bridge Replacement
This paper discusses the design of the main spans and approach spans for the replacement of the Talmadge Bridge for the Georgia Department of Transportation. The design of the concrete...
Behavior of RC Beams under Sustained Load
Experimental results of eight reinforced concrete beams under 3-month's sustained load, with the ratio of shear span to depth equal to 2.5, are reported. It is shown by tests that the...
