Composite Beams: Redistribution, Reliability, and Lateral Buckling
Research relevant to three aspects of the design of composite beams for ultimate limit states is summarized. These are: the redistribution in continuous beams and in framed structures...

Composite Space Frame?Experimental/Analytical Study
This paper describes work carried out on a composite space frame system. The system, previously developed for roof construction, comprised a pyramidal arrangement of steel angles and circular...

Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...

Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...

Steel Panel Encased R.C. Composite Shear Walls
In order to make clear the fundamental resisting mechanisms of composite shear walls, tests are carried out on the composite unit rigid frames with various infilled shear walls. Composite...

Effects of Connections on Composite Frames
This paper summarizes the preliminary findings from an experimental and theoretical study of the influence of composite connections on frame behaviour. The first part of the work included...

Steel Exoskeleton Defines Architecture
The Hotel de las Artes multi-use complex in Barcelona, Spain consists of a luxury hotel/apartment tower, a commercial office building, retail, parking and other amenities. The most prominent...

Removal, Replacement and Rehabilitation of Concrete Slabs
The project involved existing one-way slabs experiencing severe corrosion damage. The slabs were removed and replaced while salvaging the concrete beams and frame components. Significant...

Automated Design of the Steel Box Girder Guideway for the Kuala Lumpur Downtown People-Mover
Design of the Kuala Lumpur (KL) Downtown People-Mover had to be accomplished on a fast-track schedule. The system contractor assembled a team of experts from North America and Malaysia...

21st Century Timber Engineering
Timber engineering is moving into the 21st Century faced with challenges in technology, governmental mandates and environmental concerns. Engineers are continuously being challenged in...

Airport Towers: A New Generation
Airport control towers are a unique building type with monumental significance, both for the cities that own and operate the airports, and for the FAA which owns and operates them. Airport...

Harry Seed, Liquefaction & the Gravel Drain
The late Professor Seed of the University of California at Berkeley established criteria for gravel drain design in a 1977 ASCE paper. Without historical proof for its viability in a real...

Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...

Functional Analysis in Continuum and Structural Mechanics
Following brief historical remarks, the equations of the hypercircle and hypersphere of Prager and Synge and associated formulae for pointwise bounds are derived. The application of the...

Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...

Genesis: The Creation of a Lunar Base
A lunar basing scenario that utilizes lunar resources to manufacture lunar concrete modules is considered. An eleven year basing program, starting with initial robotic exploration and...

Human Habitat Design for the Space Exploration Initiative
The design of spacecraft to accomodate humans for long lengths of time e.g. conjunction-class human missions to Mars, must carefully consider both the physical and mental health of the...

Design Concepts for a Lunar Concrete Production Facility
This paper discusses concrete production fundamentals on the earth and identifies applicable features required for lunar concrete production. Production principles unique to the lunar...

Human Exploration of Mars: The Role of a Mars Outpost Laboratory
The scientific exploration of Mars will require a systematic series of reconaissance missions (robotic and human) and detailed exploration at specific sites. The detailed exploration will...
