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...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
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...
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...
Flexible Porous Breakwater
This is a theoretical study of the reflection and transmission of linear waves by a flexible, porous and thin beam-like breakwater held fixed in the sea bed. The breakwater is idealized...
Multiple Modes of Steady-State Slide-Rock Response
The dynamic response of free standing rigid bodies to base excitation can be quite complex, as evidenced by the five motions or modes to be considered in a two-dimensional analysis: rest,...
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 Systems of Rigid Bodies by Bounding Theorems
The stability of systems of systems of rigid bodies subjected to conservative and dissipative forces is investigated by considering the minimization of a work function subject to the kinematic...
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...
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...
Lunar Oasis
The Lunar Oasis emphasizes development toward self-sufficiency in order to reduce dependence on the Earth for resupply and to enable expansion utilizing indigenous resources. The Oasis...
Building a Space Infrastructure: The Reclamation Experience
The third and last duty of the ... commonwealth is that of erecting and maintaining those public institutions and those public works, which, although they may be in the highest degree...
A Horizontal Inflatable Habitat for SEI
The inflatable habitat described in this paper is a horizontally-oriented cylindrical pneumatic structure. It is part of NASA's ongoing effort to study inflatables as alternative habitats...
Hedratecture in Severe Climates
