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...
Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...
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...
Recent Advances in 3D Non-Linear FE-Analysis of R/C and P/C Beam Structures
A new simple modelling of interface problems in non-linear FE-analysis of reinforced concrete (R/C) and prestressed concrete (P/ C) structures is presented. It consists in taking account...
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....
A Probabilistic Approach to the Response of Tall Buildings to Wind Loadings
Tall buildings constructed in recent years are light in weight, flexible and low in damping. This is the consequence of using lighter material with higher strength, and fewer interior...
Surface Pressures on the Roof of the Texas Tech Experimental Building: Model and Full-Scale
Field Experiments for Wind Effects on Low Buildings
Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...
Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...
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...
Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...
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...
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...
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...
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...
