Wind Performance of Asphalt Roofing Shingles
Pre-seal and post-seal wind resistance of asphalt roofing shingles is discussed. A test method for evaluating pre-seal wind damage is described. Wind tunnel testing results are presented...

Ballasted Single Ply Design Guide Development
A new roofing concept called ballasted single ply has now captured about 25% of the new and retrofit flat roof market. This concept relies on the use of ballast to provide the wind resistance...

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...

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...

Overview of Published Documents for the Evaluation of Existing Buildings
Presently, the most common procedure used by engineers to evaluate existing buildings is probably a code approach that was developed for the design of new construction. Many engineering...

Seismic Evaluation of Buildings in the Eastern and Central United States
The Applied Technology Council (ATC) has developed and published a methodology, ATC-14, for evaluating specific buildings that is tailored for use by practicing structural engineers. ATC-14...

Retrofitting Existing Seismically Hazardous Buildings
This paper presents a brief overview of the types of problems encountered in retrofitting of existing seismically hazardous buildings. Included is a description of the various types of...

The New 1988 SEAOC Blue Book and 1988 UBC Overview of Lateral Force Section
This paper presents an overview of the lateral force section of the new seismic design provisions of the 1988 edition of the Uniform Building Code (ICBO, 1988), and the 1988 Blue Book...

The 1988 UBC Seismic Provisions for Steel Structures?An Overview
This paper will give the reader an introduction to the seismic design provisions for steel structures in the 1988 Uniform Building Code. Chapter 27 in the 1988 UBC now contains over ten...

Concrete Structures?1988 UBC Seismic Provisions
This paper discusses the special requirements in the 1988 edition of the Uniform Building Code concerning reinforced concrete structures resisting forces induced by earthquakes. The provisions...

1988 Provisions for Masonry Design
The 1988 Uniform Building Code has seen a significant change in the seismic design requirements, Chapter 23, for the design of structures subjected to earthquake loads. This paper discusses...

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...

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....

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'...

Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...

The National PDES Testbed?An Overview
Product Data Exchange Specification (PDES) is an ambitious project with the goal of developing a standardized format for representing and exchanging information about almost any manufactured...

A Survey of CASE Tools
This paper will trace the history of Computer Aided Software Engineering (CASE), describe CASE tools at each stage of the software engineering evolution, and discuss the future and trend...

The Portability of Graphics Package Dependent Software
Currently at the University of Wyoming a research project is under way to investigate methods of reducing the portability problem in software design. The project entails a general functional...

Adaptation of ANSI Standards for Communications Testing in the Connectionless Environment
American National Standards (X 3.102 and X 3.141) establish a uniform means for specifying, assessing and comparing performance of data communications systems and services from the point...
