Stability of Lift Slab Structure During Construction Stage
The lift slab structures impose stability problems during the construction phase. The process of constructing this type of structure requires placing the masses of the floor slabs at a...
A Multimedia Learning Environment for Statics
A multimedia learning environment (MLE) is being developed in the area of statics within the framework of SUCCEED's Curriculum 21. An overview is presented which includes: discussions...
Multimedia Technology and Structural Steel Design
A project is underway at The Pennsylvania State University to produce Steel Design Educational Module (SteelDEM) software. This intelligent tutor and teaching aid utilizes the state-of-the-art...
A New Laboratory for Teaching Structural Engineering
A new, practical, computer-assisted laboratory, 'AN/EX,' has been developed for teaching structural engineering. Specifically, AN/EX has been developed to encourage cross-verification...
COAST Educational Program for Teaching Structural Analysis
The paper presents a computer program designed as a teaching aid for structural analysis and finite element courses. The main objective of the program is to illustrate major steps and...
Seismic Response Studies on a Two Span Slab-On-Girder Bridge
A new type of self-equilibrating snap-back (quick-release) test setup is employed to investigate the transverse dynamic response of a two-span continuous slab-on-girder highway bridge....
Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
Seismic Study of Historic Bridges in Eastern United States
The main objective of this paper is to study the Barrackville bridge and its response in resisting static and seismic loads. Since the design was based on controlled deflections, the analyses...
Progress in Reinforced Concrete Column Design
This paper reviews some of the design procedures used for both braced and unbraced frames constructed in reinforced concrete. The discussion refers to the problems of material and geometric...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
Load and Resistance Factors for Bridge Design Code
The paper summarizes the code development procedures used for the new LRFD (load and resistance factor design) bridge code. The current specifications use allowable stresses and/or load...
Assessment and Upgrade of an Older Transmission Line
This paper discusses the various tools and procedures which have been used to assess and upgrade an older 130 kv tower line. The purpose of the assessment was to determine the line compliance...
Lateral Load Resisting Systems for Circular Buildings
The design of structural systems to economically limit inter-story drift and building acceleration for circular high rise buildings is presented within the framework of two recently constructed...
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Limit States Analysis of Masonry Arches
The limit states analysis of masonry arches, heretofore used only for the analysis of hinging mechanisms within the arch ring, is shown to have wider applicability. Lower and upper bounds...
Steel-Concrete Interaction by Means of Film Sensors
By adapting a recently-developed technique based on the piezoelectrical properties of relatively thick films made of Polyvinyldifluor organic composites and extensively used in robotics,...
Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...
Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...
Characterization of an ER Active Member
In the presence of strong electric fields (kV/mm), electrorheological (ER) materials change form viscous fluids to yielding materials. The class of ER materials used in this study have...
Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...
