On-Orbit Assembly of Large Space Structures: A Mars Aerobrake Mock-up Study
As design requirements for space structures become larger in dimension, the issues of shipping and assembling these structures in space become more critical. One example of such a structure...
Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...
A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...
The Analysis Related to the Impact of Composite Panels
In analyzing experiments under impact loading, a dynamic model is needed to solve for the deflections and strains as functions of time. For composites, where shear deformation can be very...
Operations Planning for Space Station FREEDOM?and Beyond
Automated planning and electronic execution systems offer tremendous potential for enhancing operations aboard Space Station FREEDOM (SSF). To exploit this potential, the Operations Planning...
The German Participation in the Soviet MARS 94/96 Mission
The German contribution to the science program of the Soviet MARS 94/96 missions includes 14 experiments or experiment, participations to be placed on the various mission elements: the...
Preliminary Investigation of a Lunar 16 Meter Optical Telescope
The results of a year-long effort to develop a design concept for the structure of a 16 meter lunar optical telescope are presented. Various mounting configurations and mirror configurations...
Reliability Consideration in Shakedown Analysis
Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual...
Reliability of Nonlinear Frame Structures by SFEM
A method is proposed for the reliability analysis of nonlinear frame structures with flexible connections. The uncertainty of a connection is represented by a group of random moment-relative...
Crane Raise with Zero Downtime
Massachusetts Fort Authority (MPA) was faced with a dilemma. Its Conley Terminal tenants needed higher cranes but could not relinquish the cranes for more than a few days at a time. No...
Earthquakes: A New Look at Cracked Masonry
Economics, fears of liability, and a strict damaged-buildings repairs ordinance have contributed to an extensive delay in the repair of masonry-infill buildings in earthquake-stricken...
Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...
Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....
Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
Discrete Optimal Design of 3D Frameworks
The paper describes a discrete optimization method for the least-weight design of three-dimensional (3D) steel building frameworks. The method involves the coordinated application of structural...
