Seismic Safety Regulation of Existing Structures
Establishment of standards for seismic strengthening of existing buildings has been difficult since full compliance with current codes is generally too expensive. A general consensus has...
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...
Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...
Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...
Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...
Shake Table Testing of a Friction Pendulum Seismic Isolation System
Building models using the Friction Pendulum System (FPS) were tested on the shaking table at the Earthquake Engineering Research Center of the University of California, Berkeley. This...
Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...
Inelastic Seismic Design of Concrete Structures
This paper provides an overview of the state-of-the-art publication on the same subject under preparation by ASCE-ACI Committee 442's Ad Hoc Subcommittee on Inelastic Response...
Inelastic Seismic Analysis of Concrete Buildings
The important inelastic analysis techniques that are suitable for concrete buildings subjected to earthquakes are summarized. Basic principles and practical modeling guidelines are given...
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...
Bermed Shelters Subjected to Accidental Explosions
An investigation of the adequacy of two competing shelter designs to protect the occupants from an accidental explosion in a nearby shelter is described. Two bermed shelters, one of rectangular...
Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...
Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...
Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...
SDOF Structural Response Model Accounting for SSI
This paper outlines the theory associated with single-degree-of-freedom (SDOF) structural response models which account for soil-structure interaction (SSI) and evaluates the performance...
Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...
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),...
