A Study of Australian Glulam
Australia and New Zealand are debating how they should develop a new specification for structural glulam to replace AS/NZS 1328.1:1998. The new document will include i) performance requirements and ii) methods...

Flexural Behavior and Single Fiber-Matrix Bond-Slip Behavior of Macro Fiber Reinforced Fly Ash-Based Geopolymers
A study on flexural response and single fiber-matrix bond-slip behavior in fly ash-based geopolymer reinforced with different types of macro steel fibers is presented. Although direct correlations between bon...

Chapter
Composite Beams
Composite flexural members are composed of two separate concrete placements that are connected to behave as a single beam element; the separate elements can be either precast or cast-in-place. The most common for...

Chapter
Axially Loaded Members
The primary motivation in prestressing concrete is to offset tensile stresses that develop in flexural members. Consequently, using prestressed concrete in members that are largely loaded in axial compression ...

Chapter
Comprehensive Problems
Design of prestressed concrete is more intense than design of reinforced concrete and requires more checks and adjustment of reinforcement. The following comprehensive problems are developed to allow mastery o...

Chapter
Connections and Anchoring to Concrete
Structures require members to be connected and loads to be transferred. These loads can be simple bearing, cast-in-place continuous joints, or mechanical attachments. Three tools assist in connection design: shea...

Chapter
Basic Concepts
Most concrete construction in the world is cast-in-place reinforced concrete. In reinforced concrete structures, steel reinforcement is placed into the concrete to provide the tensile resistance to flexural loads...
-
Chapter
Materials
The primary material considerations for prestressed concrete structures are the mechanical properties and durability of concrete, prestressed and nonprestressed reinforcement, and anchorage devices. The first ...

Chapter
Flexural Basics of Analysis and Design
Analysis and design are two interrelated activities. Analysis is the determination of the effect of loads in a member based on the given properties and applied loads. Analysis is typically a deterministic process...

Chapter
Shear and Torsion
The behavior of beams and slabs in flexure is well understood and is generally predicted with satisfactory margin of error as reflected by the strength reduction factor. Flexure is considered on a section basi...

Chapter
Continuous Slabs and Beams
Continuity provides an economic benefit with shallow sections and longer spans possible. Continuity also inherently improves safety due to the redundancy provided by the continuity. This comes at a price of in...

Chapter
Strut-and-Tie Method
Beam theory, including the assumption that plane sections remain plane, does not apply at points closer than the distance h to a discontinuity in applied load or geometry. This leads to the identification of disc...

Chapter
Prestressed Concrete Applications
Prestressed concrete is adaptable to a wide variety of structural systems. These include pretensioned and post-tensioned structures, both cast-in-place and precast, and other prestressed elements in conjunctio...

Chapter
Partial Loss of Prestress
Prestressing a concrete member effectively applies a substantial axial force to the member that is in place for its entire service life. In both pretensioned and post-tensioned methods of prestressing, this pr...

Chapter
Flexure: Design
Structural design involves determining the section and material properties followed by prestress details to satisfy serviceability, strength, and detailing. The process typically begins by validating that serv...

Chapter
Camber and Deflections
The primary purpose of prestressing concrete is to increase the load at which the concrete cracks. The consequence is that, depending on the choices made by the engineer, the section remains uncracked over a m...

Chapter
Two-Way Slabs
Prestressed concrete slabs are used in buildings, parking garages, roofs, decks, and other similar applications. They may be either one-way slabs, spanning in predominately one direction, or two-way slabs, spanni...

Chapter
Spliced Girders
Precast, prestressed girders are widely used in buildings and bridges; however, one of their main limitations is the length of the span that can be shipped or the capacity of a simple span beam. AASHTO girder ...

Experimental and Numerical Investigation of Innovative Composite Buckling-Restrained Fuse
Fuses or sacrificial elements are the weakest part of a structural member that are designed to localize potential failure within themselves. These elements are used to dissipate the energy of a severe lateral ...

Modal Parameter Identification of an Electrical Submersible Pump Installed in a Test Well Using Drop Tests
Electrical submersible pumps (ESPs) are used in the petroleum industry to pump large amount of fluids from subsea deep wells. Currently, ESPs are responsible for approximately 10% of the world’s crude oil pro...
