Flexural Behavior of Slender Post-Tensioned Masonry Walls
The 2002 edition of the Masonry Standards Joint Committee (MSJC, 2002) design provisions for masonry structures includes a chapter on the design of post-tensioned masonry (PTM) walls with...
Overview of Structural Behavior of Members Subjected to Torsion
The torsion strength of concrete beams depends on many factors, such as the amount of reinforcement, the volumetric ratios of longitudinal and transverse steel bars, the concrete strength,...
Advances in Analytical Modeling of Torsional Members
The basic formula for calculating the torsional strength of reinforced concrete members was developed by Rausch (1929) using the space truss concept. Unfortunately, Rausch's equation may...
Detailing and Design Examples for Torsional Members
The nature of the internal force flow in a concrete member subject to torsion brings about both longitudinal and transverse force components. The resulting tension brought about by the...
A Tale of Two Towers: The Foundations
In preparing two lots in New York City's Times Square as sites for modern skyscrapers, engineers devised foundations and structural systems that would allow for subway lines,...
A New Identity
By repairing and relocating steel trusses, replacing deteriorating approach spans, and replacing what, at the time of its construction, was regarded as a daring concrete truss, engineers...
Outside the Box
Employing an innovative design that made construction quick and economical, the box girder structure carrying Highway N-2 over interstate 80 near Grand Island, Nebraska, became the first...
Case Studies in Steel
An innovative project delivery system for structural steel buildings enables the structural engineer to provide complete structural design services on conventional contractor-led design/build...
Par Excellence
A 50-year-old Brownfield with a mountainous pile of steel slag has been remediate and developed into a recreational site that boasts a free golf course for inner-city youth, a championship-quality...
