Behavior of a Crack Under Reversed Cyclic Loading
The results of two series of basic experimental studies for opening and closing behavior in RC members are reported. For the first series, axial forces were applied to the specimens in...

Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...

Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...

Analysis and the Design of Multi-Layer Viscoelastic (V.E.) Dampers for Tall Structures
Vibrational motion of tall buildings can be damped by employment of viscoelastic passive dampers in the structure. The type of dampers selected depend on locations where relative displacements,...

Unsteady Aeroelastic Base Moments on a High-Rise Building
To consider aeroelastic instabilities of prismatic structures in winds, i.e., vortex induced vibrations or galloping oscillations, unsteady aeroelastic forces must be investigated as the...

Status of Structural Engineering Research
Problems and opportunities for structural engineering research are being addressed in a study by the ASCE Structural Division Task Committee on Structural Engineering Research Needs/Funding....

An Education in Tunneling
In this follow-up to the author's article in the April 1989 issue of Civil Engineering, this senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering...

Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...

Reliable Displacements from Integrated Quick-Release Accelerograms
A new baseline correction method has been developed which allows accelerograms collected during quick-release tests of full scale structures to be doubly integrated to displacements. The...

Forced Vibration of Sliding Base Structural Systems
An analytical and experimental study of the effect of a horizontal sliding plane on the dynamic response of a single-story structure subjected to harmonic motion is presented. There is...

Friction-Dampers for Economic Seismic Design
A novel structural system, which combines the strength and stiffness of a braced frame and energy dissipation capacity of the friction-dampers, has been used in the design of a reinforced...

System Identification of Meloland Road Overcrossing
The Meloland Road Overcrossing (MRO) is a two-span reinforced concrete bridge structure located east of El Centro, California, 0.3 mi from the Imperial Fault. The Imperial Valley Earthquake...

System Identification of a Large Structure Using Pseudo-Dynamic Test Data
This paper deals with structural modeling and the determination of optimal nonlinear models by applying system identification techniques to inelastic pseudo-dynamic test data from a full-scale,...

Tradeoffs Between Active Control and Identification of Structural Systems
This paper explores the tradeoffs between structural identification and structural control in a quantitative manner. Through the intemediary concept of an optimal input, it is shown that...

Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...

Seismic Isolation of a Flight Simulator Manufacturing Facility
The corporate headquarters of Evans & Sutherland is located in the University of Utah Research Park which is in Salt Lake City, Utah. A major fault runs through Salt Lake City...

Seismic Repair, Restoration and/or Upgrading of Existing Buildings
The ultimate goal of this paper is to discuss the selection of the most efficient (optimal) strategies and techniques for upgrading an existing building. To achieve this goal, it was considered...

Historic Background of Seismic Construction in San Francisco
A seismic design and construction tradition has developed in California because of the unique experience with local earthquakes. After the 1906 earthquake and fire, building performance...

Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...

Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
