Pressure Measuring System for Wind Loads
A project to acquire wind and building surface pressure data in the field is continuing at Texas Tech University. A test building of dimensions 30 ? 45 ? 13 ft (9.1 ? 13.7 ? 4.0 m) and...

Instrumentation of the Shenyang T.V. Tower
The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced...

Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...

Use of Experimental Data to Develop Probable Behavior
The intent of this paper is to present results of research that studies the performance of the University of Colorado walls tested by Professor Benson Shing. These walls would be classified...

Dynamic Response Prediction for Earthquake Resistance Design of Bridge Structures
Newly developed nonlinear analysis procedures for assessing the earthquake resistance of bridges have been incorporated into the computer program SEISAB (SEISmic Analysis of Bridges)....

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...

Vertical Response Data from the Dominion Road Bridge Test
In January and February of 1985, two bridges were tested in New Zealand using simulated earthquake loads. The objective was to determine the in-situ seismic response of two reinforced...

Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...

Experimental Study on Structural Control for Seismic Loads Using Passive and Active Devices
The feasibility of controlling the responses of structures against seismic loads is investigated through some experiments and numerical analyses for both the passive and active control...

ATC 14: A Methodology for the Seismic Evaluation of Existing Buildings
A new method for evaluating the seismic resistance of existing buildings has been developed based on the historic performance of buildings in past major earthquakes. This methodology identifies...

Consequences and Achievement of Supplemental Damping for Improved Seismic Performance
An earthquake resistant design philosophy which relies upon increased stiffness and damping rather than increased strength and ductility has been investigated. The effect of adding supplemental...

Some Significant Records from Instrumented Structures in California?USGS Program
The main objective in seismic instrumentation of structures is to facilitate response studies that lead to improved understanding of the dynamic behavior and the potential for damage to...

Seismic Instrumentation of Buildings in Italy
The paper describes the philosophy of the ENEA project of seismic instrumentation of buildings in Italy and the steps made to implement it. The philosophy is twofold: i) to define a general...

Architectural Configurations in Vina del Mar
This paper identifies the architectural characteristics of 121 reinforced concrete buildings in Vina del Mar. These characteristics are related to the damage statistics for the building...

Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...

Implications for Limit State Design of Inverted V Braced Steel Structures
Inverted V braced steel structures with backup ductile moment-resisting frames forming a dual system, exhibit complex inelastic behavior under severe seismic excitations. Thus, current...

Building Frames Subjected to 2D Earthquake Motion
Inelastic response of a simplified model of a 10-storey building frame was analyzed to assess the effects of bi-directional seismic loading. Interaction between the strengths in the two...

Seismic Load Effects on a Scaled Model Structure
A long term observation on a scaled steel braced frame model with intentionally reduced seismic strength is ongoing since 1983. This paper examines the seismic load effects of two earthquakes...

Detection of Seismic Structural Damage
Damage analysis models based on equivalent modal parameters are used to identify the serviceability limit state for structures subjected to earthquake loads. A model for the analysis of...

A Damage Model for Reinforced Concrete
The damage index developed by the authors models concrete damage as a low-cycle fatigue phenomenon. By quantifying the energy dissipated as a fraction of the total energy dissipation capacity,...
