Where do the Arrows Come From? Evaluating Structural Loads
Two elements of an undergraduate's structural education that are not treated well in most textbooks are (1) the development of correct loads and (2) load modelling-that is, how the load...

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...

Teaching Structural Loading: A Case Study
CVEG 4803: Structural Loading course was formulated three years ago as an undergraduate senior elective course. In this course structural dynamics is introduced for one third of the course....

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...

Experimental Measurements of Dynamic Loads Imposed by Moving Crowds
Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of...

Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...

Long-Term Monitoring of Civil Structures using Smart Structures Techniques
A smart monitoring program for a hybrid concrete-steel building in Washington, D.C. has been developed. The building is currently being instrumented with a variety of strain and corrosion...

Design and Construction of Post-Tensioned Concrete Floor Systems
This is a summary of the original full length paper which is available from the author. This paper assumes a basic technical knowledge of reinforced concrete design and prestressed concrete...

Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...

Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...

Prestressed Concrete Failures Due to Uplift
The paper presents some examples of prestressed concrete DOUBLE-TEE (DT) failures caused by hurricane Andrew. The DT's failures was mainly due to the negative moment created by uplift....

Reliability Analysis of Stiffened Panels
This paper presents a methodology to assess the reliability against collapse of structural members, as typified by the buckling collapse of stiffened deck panels in ship structures. This...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

Cyclic Performance of Riveted Connections
As part of a larger experimental project on seismic performance of older steel frames, seven concrete-encased and unencased connections were tested. The specimens consisted of both riveted...

Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...

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...

Analysis of Unstiffened and Stiffened Tubular Members Under External Pressure and Structural Loads
This paper summarizes some important results concerning the ultimate capacity of stiffened and unstiffened tubes under combined loading. Such tubes are candidates for use in offshore structures...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

Compressive Strength of Large Scale HSLA-80 Steel Cellular Sections of a Double Hull Ship Structure
An analytical and experimental large scale test program was conducted to investigate the instability failure modes of cellular double hull box sections. The main emphasis of the study...
