A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...

Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...

Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....

Temporary Structures for Protection and Access
Temporary Structures in Construction Projects (TSC) are utilized for three (3) purposes A. Support (of the structure being built or adjacent structures or utilities) B. Protection (of...

Fall Protection & Debris Containment During Construction
The purpose of this paper is to review the current practices in the United States for both fall protection and debris protection during high rise construction. A performance comparison...

Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...

Performance of a Prestressed Rigid Frame During Removal of Column 6W from I93 in Boston, Massachusetts
The first phase of the suppression of Boston's Central Artery included the Early Viaduct Construction in the Central Artery North Area. This project required that Column 6W...

Permanent Structure as Part of the Underpinning System for Boston's Central Artery
The Central Artery, a major six lane structural steel viaduct, has been one of Boston's most significant roadways over the past three decades. Increasing congestion, accidents,...
