Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...
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)....
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Heath Building?Load Paths of an Underpinning
A case study of an underpinning is presented which, in principle, consists of the introduction of a transfer system in an existing building. The transfer system modifies the load paths...
Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...
Standards for Design Loads During Construction: An ASCE Effort
ASCE embarked on a new standards activity by the Design Loads for Structures During Construction Standards Committee. The objective of the effort is the development of standard guidelines...
Remote Automatic Data Acquisition Systems
Personal computers have been used on two projects to monitor peformance of structures in an automatically triggered mode. In both cases a local PC is used to continually monitor a triggering...
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...
Discrete Field Stability Analysis of Latticed Towers
The design of latticed towers is often controlled by the stability of the overall system as opposed to local member buckling. The purpose of this paper is to develop an elastic stability...
An Overview of the U.S. Coordinated Program for Masonry Building Research
The U.S. Coordinated Program for Masonry Building Research is a time-phased set of specific research tasks addressing materials, component and system behavior. The objective of the program...
Influence of Nonlinear Models on Dynamic Displacements
This research is a part of an ongoing multi-year program that is sponsored by the National Science Foundation and conducted under the TCCMAR (Technical Coordinating Committee for Masonry...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...
Rapid Visual Screening of Buildings for Potential Seismic Hazards
A Rapid Screening Procedure (RSP) developed for use nation-wide is based on a 'sidewalk survey' of a building, in which a Data Collection Form is completed by...
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...
ATC-22: Development of a Handbook for ATC-14
The ATC-22 project is the development of a Handbook for the application of the methodology of ATC-14 for the seismic evaluation of existing buildings. The development of the Handbook itself...
Postearthquake Safety Evaluation of Buildings
Procedures for the safety evaluation of buildings in earthquake damaged areas have been developed. Two evaluation techniques, Rapid Screening and Detailed Inspection, are described. Rapid...
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...
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 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,...
