Comparisons of Full Scale and Wind Tunnel Model Response to Wind of Long Span Bridges
There are several vital reasons for measuring the response of full scale structures to wind and comparing the results to models - both experimental and analytical - employed in design....

Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...

Transient Response of Wind-Induced Internal Pressures in Buildings
The paper refers to a new experimental approach applied in a boundary layer wind tunnel experiment to test the transient response of the wind-induced internal pressure in a building when...

The Application of Aerodynamic Model Tests to Wind Loading of Tall Buildings
The theory of the aerodynamic model test, in which the wind response of tall structures can be computed for a range of dynamic properties from a measurement of the external wind load,...

Field Experiments for Wind Pressures
A project is underway at Texas Tech University to acquire wind and building surface pressure data in the field. Objectives of the project are to obtain a reliable data base for external...

Wind Forces Measured on a Tall R.C. Chimney
This paper describes some aspects of an analysis performed on measurements of a variety of parameters relating to the wind, wind forces on and the response of a tall chimney. The results...

Research Needs to Resist Terrorist Attacks
The task of protecting facilities against terrorist attacks is very much a new problem for the U. S. civilian sector. Guidance as to what steps need to be taken by a municipality or a...

Suspended Polycarbonate Shield to Defeat Terrorist Threats
The Navy Civil Engineering Laboratory is conducting research on a window concept that offers great potential for overcoming the disadvantages of blast resistant windows. The concept is...

Response Charts for Designing Against Nuclear Overpressures
The single-degree-of-freedom equation of motion for an elastic-plastic system with a nuclear airblast overpressure forcing function is nondimensionalized and solved. Solutions are presented...

Limiting Performance and Design by Reanalysis of Structures for Blast Resistance
Limiting performance is the absolute optimal response of a structure under a specified transient load. Reanalysis methods are computational techniques for analyzing locally modified large-scale...

Drop Test of Dolos Armor Units
Dolosse are concrete armor units used for the cover layer on many breakwaters and jetties. In order to study their complex loads and structural response, a prototype study at Crescent...

Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...

Wind-Induced Response of a Tall Building and Comparisons With Wind Tunnel Predictions
This paper describes the measured wind-induced response of a tall office tower and comparisons made with wind tunnel studies of the building. The use of an innovative structural system...

Rational Design Approach for Tension on the Net Section
A study of the bearing and net section capacities of bolt connections for material thicknesses encountered in cold-formed members was conducted. This paper summarizes the findings as they...

Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...

Moment Rotation Curves for Double Framing Angles
Moment-rotation curves for bolted framed steel connections are derived from force-deflection data obtained from laboratory tension and compression tests of angle segments. These derived...

Beam-Columns
The Fourth Edition of the SSRC Guide presents a state-of-the-art information on beam-columns for use by specification writers, researchers, and designers. The present paper is an extremely...

Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...

Cumulative Damage of Structures
Structural response records may be analyzed to estimate relative motions of civil engineering structures. Several methods are available for the estimation of cumulative damage on the basis...

Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....
