LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...

Reliability Models for Bridge Structures
The development of rational design criteria requires efficient measures of structural performance. Traditional methods of analysis do not reveal the actual safety reserve (degree of redundancy)....

Inelastic Performance of Single-Story Masonry Shear Walls
Twenty-two story-height reinforced masonry shear walls have been tested to examine the influence of the applied axial stress, and the amount of vertical and horizontal reinforcement on...

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)....

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-23: A Survey of California Hospitals for Earthquake Survivability Potential
In September, 1986 the SSC recommended the completion of a survey of existing acute care hospitals as the first step in a program to bring about the upgrading of all pre-1973 hospitals...

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...

Earthquake Damage Estimates of Conventional and Isolated Structures
The philosophy inherent in current seismic design codes for buildings accepts the premise that there will be both structural and non-structural damage but that life safety will be preserved....

Earthquake Resistant Design Using Friction Pendulum Connections
The Friction Pendulum System (FPS) offers a simple approach for increasing a structure's earthquake resistance. The approach uses steel connections which absorb earthquake...

N-Pad?A Three-Dimensional Program for the Analysis of Base-Isolated Structures
N-PAD is a three-dimensional computer program especially written for the analysis of base-isolated structures. The program is designed with the ability to model various types of isolation...

Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....

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 Design of Highrise Building with Mega Frame
The NEC corporation head office building is under construction at Shiba Minato-ku, Tokyo, Japan. This building is a highrise building of steel structure with the height of 180m. The structural...

Seismic Design of a Long-span Space Structure
This structure consists of a 5 layered complex shape of long-span steel roof structure, and reinforced concrete (RC) and steel reinforced concrete (SRC) supporting structures. The roof...

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...

Normalized Damage Index for Evaluation of Buildings
A conceptual model for evaluation of structural damage is developed based on the fundamental idea of demand and capacity. The proposed formulation combines two recognized sources of damage:...
