Interpretation of Nondestructive Integrity Tests Using Artificial Neural Networks
A barrier to more frequent use of nondestructive integrity tests on cast-in-place foundations is the difficulty of interpreting the test results to identify the presence or absence of...
Experiences with an Undergraduate Structural Engineering Laboratory
An Undergraduate Structural Engineering Laboratory was recently implemented at Lehigh University with funds obtained from the National Science Foundation through its instrumentation and...
Sensors and Techniques for Structural Monitoring
This paper summarizes measurement requirements for the monitoring of engineering structures and describes new sensor/system configurations that are finding useful application in field...
Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...
Seismic Retrofit of R/C Columns with Inadequate Lap Splices
This paper presents experimental results on the use of rectangular steel jackets to improve the seismic performance of rectangular steel jackets to improve the seismic performance of rectangular...
Seismic Renewal of Civil Infrastructure Systems
Almost all civil infrastructure systems are vulnerable to natural hazards such as earthquakes. The paper presents a broad perspective of the research needs for seismic renewal of the infrastructure...
Some Aspects of Compression Member Design in Australia
The paper summarizes and elucidates the provisions of the Australian Standard AS4100-1990, Steel Structures, for the design of compression members. Emphasis is placed on those aspects...
Design of Half-Through or Pony Truss Bridges Using Square or Rectangular Hollow Structural Sections
The initial part of this paper will outline some of the research, testing, and investigation which has been done on half-through truss bridges. This research is primarily concerned with...
Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...
Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...
Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...
Experimental Study on the Strut Type of Cable Net Membrane Structures
In this paper a new type of suspension membrane structure combined with a cable net is proposed, in which the supporting struts are arranged between the membrane surface and the cable...
Form Finding Numerical Methods for Tensegrity Systems
The rigidification of Tensegrity Systems is related to selfstress states which can be achieved only when geometrical and mechanical requirements are simultaneously satisfied. This paper...
Seismic Performance and Retrofit of the Golden Gate Bridge
Since its opening in 1937, the Golden Gate Bridge has endured and functions as an important transportation link for Bay Area commerce and commuters. After an earthquake in 1989, T.Y. Lin...
Akashi-Kaikyo Bridge Underconstruction
This paper presents 1) brief history of the survey work, 2) brief description of the physical dimensions and structural system, 3) major studies for the design, 4) development of higher...
Lateral Response of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This project addresses the out-of-plane response to lateral loading...
Optimization for Earthquake Loads
Structural optimization for seismic loads can be approached from a deterministic or nondeterministic point of view. Deterministically, the major difference between optimization of statically...
Flange Local Buckling and Behavior of I-Sections
A simple kinematic model is proposed to determine the locally buckled shape of the compressive flange plate of I-sections subjected to pure bending or bending combined with axial thrust....
Boundary Forcing and a Dual-Mode Calculation Scheme for Coastal Tidal Models Using Step-Wise Bathymetry
Tidal energetics are persistent and important factors in almost all coastal regions. As such, it is important to employ techniques that can consistently reproduce observed tidal variations....
A Field and Modeling Study of Residual Circulation in Sarasota Bay and Tampa Bay, Florida
Based on analysis of current data at three distinct locations within the Sarasota/Tampa Bay system, we defined the residual circulation patterns and the relative influences by tides, wind...
