Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...
Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...
Behaviour of Concrete Masonry Infill - Steel Frame Structures
Twenty-eight masonry shear panels infilled in steel frames were tested to ultimate strength under in-plane, horizontal loading applied at roof level. The parameters investigated in this...
Experimental Evaluation and Finite Element Analysis of Masonry-Infilled R/C Frames
Eleven tests were conducted on 1/2-scale, single-story infilled frame specimens to study the influence of the relative strengths of the infill panels and the bounding frames and the frame...
How to Optimize Frames Using Plastic Design Concept
An optimal design procedure using plastic design concept was presented. For low-rise building frames, optimal plastic designs can be made using the plastic limit load as a basis of design....
RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...
Plate and Frame Membrane Air Stripping
This paper examines utilization of a plate and frame membrane air stripping system for the removal of volatile organic chemicals (VOCs) and radon from a water supply. Previous work explored...
Engineering, Construction, and Operations in Space IV
This proceedings,
A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....
Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...
Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...
Alternative Decisions for Space-Based Scheduling in Multi-Story Projects
SCaRC (Space-Based and Resource-Based) is a prototype knowledge-based scheduling system that acknowledges work space as a scheduling constraint. The SCaRC system comprises different scheduling...
Time-Space Tradeoff Strategies for Space-Schedule Construction
Space availability on a construction site can have a major impact on the efficiency and constructability of a project. Especially when space is limited, tradeoffs between activity sequencing,...
A Simplified Method of Multistory-frame Analysis Including the P-? Effect
A simplified method of non-iterative analysis of rigid multistory-frames having vertical columns with different heights within the same story is developed by means of a modification to...
Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...
Development of a Visual Method to Track the Movement of Hydrogen Bubbles in a Laboratory Flume
The current study proposes a visual method for tracking the hydrogen bubbles position with time in a 2-D space. The experiment is filmed from above with a video camera. The obtained movie...
Malaysia's Twins: High-Rise, High Strength
U.S. firms, following the market for new skyscrapers to Asia, are involved in design and construction of twin office towers in the commercial heart of Kuala Lumpur, Malaysia that will...
Space-Frame Pyramid
The world's largest space frame pyramid, completed at California State University in Long Beach in late 1994, proved to be a lighter weight and more economical alternative...
Alternative Habitat Concepts for the First Lunar Outpost
The First Lunar Outpost (FLO) Study was a NASA-wide effort to define systems for a near-term, low cost return to the Moon. The FLO habitat must support four crew on the lunar surface for...
