Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...
Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...
Building in Space
Work on the nation's first permanently manned space station has begun. Almost $200 million in contracts for conceptual design for the station were awarded by the National...
Changing Attitudes Towards Elevated Structures
This paper examines the reaction of professionals and politicians to specific examples of proposals for new public transport systems that entail elevated structures in central areas. When...
A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
Utilization of Experimentally Obtained Connection Data in Assessing the Performance of Steel Frames
Data from over 70 separate experimental studies on steel beam to column connections are reviewed with particular reference to the joint's in-plane moment-rotation characteristic. More...
Buckling of Flexibly-Joined Simple Frames
A nonlinear analysis of plane elastic frames is presented. The static loading consists of both eccentric concentrated loads (near the joints) and uniformly distributed loads on all or...
Behaviour and Strength of Steel Frames with Semi-Rigid Connections
A research study was started at the Politecnico of Milan (Italy) to investigate the influence of the main governing parameters on the behaviour and strength of flexible frames. A sophisticated...
Joint Flexibility in Steel Frames
This paper investigates the effects of connection flexibility and panel zone deformation on the behavior of plane steel frames. The incorporation of these factors in frame analysis will...
Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...
Load-Bearing Capacity of Masonry Walls in a Critical Buckling Condition Taking Into Account the Restraining Effect of Floor Slabs
This paper studies the buckling effect of masonry walls and concrete floor slabs as a frame system. The frame is calculated according to the theory of II. order. The buckling length, the...
Use of Computer Graphics in the Analysis of Large Space Structures
This paper illustrates how interactive computer graphics can provide a useful tool in setting up analytical models of structural latticeworks comprised of large numbers of degrees of freedom...
A Space Frame Forecast
New York City's Jacob K. Javits Convention Center has the largest space frame of its kind in the world. There are several unique design features in the space frame, among...
The Practitioner's Approach to Infrastructure Master Planning: The State of the Art
Infrastructure master planning is still a disjointed practice, but recent empirical work provides a base from which coordinated efforts, tying together the various sectors, are possible....
Connection Flexibility and Steel Frames
The papers included in this book introduce and present methodologies for the analysis and design of frames which take into account the effect of joint flexibility on the response characteristics...
