The Lunar Ultraviolet Telescope Experiment (LITE) is a feasible scientific payload which could initiate a unique ultraviolet (UV) sky survey from the lunar surface prior to our manned...

Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...

Future Launch Systems: The Policy Challenge
A review of the literature and discussions with military, commercial, and NASA representatives shows that all users agree we need new systems, but there is no agreement on which to pursue....

Space Commercialization: Problems of Law and Policy
This paper focuses on executive and legislative efforts to promote the growth of commercial space industries in the United States. After a discussion of the current, situation and efforts...

Mixed-Use Business Park Developments in Space: A Real-Estate Paradigm
Standard terrestrial business-park development practice is proffered as a realistic organizational model for expanding human activity in Earth orbit. The histories, methods and biases...

Dynamic Optimization by Small Variation of the System Layout
Dynamic problems have been usually considered in the speed for frequency domain. However, most machines, structures or mechanisms are usually interconnected subsystems, overconstrained...

ARIANE-5 Launch Operations Construction and Operation of a New Launch Complex for Lower Cost, Higher Reliability Missions
This paper describes the main criteria driving the evolution of these facilities : launch rate, vulnerability to accidents, reliability and safety, cost optimization and adaptation to...

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...

Marta North Line Midtown Station
This paper presents a case study of a cast-in-place concrete rapid transit station structure. Attention is focused on the performance of the monolithically connected, three-dimensional...

Wind Deflection Probability Analysis
A statistical analysis is performed which analyses the probability of various magnitudes of deflections of a cable-stayed roof occurring due to wind uplift. Extensive wind analyses were...

Seismic Fragility Analysis of Sheahan Pumping Building
This paper presents a seismic fragility analysis of the Sheahan pumping building located in Memphis, Tennessee. In the analysis, seismic response is determined from the response spectrum...

Seismic Analysis of Failure and Loss of Function of Water Pumping Facilities
Water company managers evaluating potential seismic damage effects on a pumping facility will require a reasonable estimate of the probable magnitude earthquake that has potential to disrupt...

Floor to Wall Anchors in Historic Brick Buildings
The poster presentation at the Structures' Congress details a retrofit analysis performed on the Gilroy Historic Commercial Building, which was instrumented during the Loma Prieta Earthquake....

Space Frame Solution for the Design of Large Pyramid Structures
This paper presents the engineering design methodology, structural analysis, system detailing, and installation procedures for a large span space frame structure currently under construction...

Roof Space Frame Design of the C.K.S. Airport Passenger Terminal II
This article attempts to provide a description of the characteristics of the Second Terminal Airport. To comply with the functional requirement of the magnificent facade and spacious design...

Deployable Mesh Reflector
This paper presents a new deployable reflector for space applications, based on a deployable edge frame that deploys and prestresses a 'rigid' cable network. The edge frame consists of...

An Application of Inverse Problem Techniques to Spatial Structures
The present paper attempts to give a definition of inverse problems for spatial structures, and to develop a design method to find the optimum configurations and shapes for such structures...

Structural Failure and Quality Assurance of Space Frames
Space frame has been developed rapidly in China and used to wide extent to cover various types of buildings. The large scale of application will unavoidably cause quality problems. Damages...

Experimental Study on a Buckling Behavior of a Wooden Single-Layer Space Frame of Reticular Shell on a Hexagonal Plan: Influence due to the Bolted Joint Looseness with Axial and Bending Resistance
The authors have investigated about the structural behavior of a wooden single-layer space frame structure with the bolted joints. We have carried out a buckling tests of a wooden single-layer...
