This standard is intended to be used by licensed design professionals (LDPs) and provides minimum requirements for the design of shallow post-tensioned concrete foundations on expansive and stable soils. Internal forces and stiffness requirements specified in this standard shall be used for design...
Summary A. This section includes repair to unbonded post-tensioning in the slabs and beams as follows: Provide listing of work tasks specific to post-tensioning that are to be described/specified in this specification, possibly including the following (modify as appropriate to identify...
INTRODUCTION This document: • Provides guidelines to aid in the evaluation of the performance of slab-on-ground foundations; • Provides guidelines to aid in the evaluation of the performance of residential and other similarly constructed low-rise buildings with slab-on-ground foundations; • Applies...
Purpose and scope This manual has been developed to provide guidance for owners, licensed design professionals (LDPs), builders, contractors, and field personnel involved in the installation, stressing, and finishing of unbonded single strand systems used in the construction of residential and...
Until now, organizations delivering data centre services focus on building highly resilient facilities by designing redundancy at various levels typically in accordance with standards such as ANSI/TIA-942*, ANSI/BICSI-002* and others. However, many organizations have come to realize that without...
These Recommendations provide practical guidance in the application of permanent and temporary prestressed rock and soil anchors using high-strength prestressing steel. They represent the current state of practice and provide recommendation for the design, installation, and testing of grouted...
This standards publication covers self-contained, electrical and electronic, wall-mounted room thermostats for controlling the temperature of the space in which the thermostat is mounted by controlling the applied energy for heating or cooling
OVERVIEW This annex provides the specifications that are required for a programmable thermostat to be classified as energy efficient.
Post-tensioning design, evaluation, and repair requires specialized knowledge. This guide is intended to provide an introduction to the techniques and procedures used to evaluate and repair unbonded post-tensioned structures. While the procedures outlined are effective on many projects, the...
Scope and overview This guide provides basic knowledge about posttensioning design and construction within the scope outlined in the following and is primarily intended for design professionals but can also be used by others involved with the design and construction of post-tensioned concrete...
Section I applies to several types of boilers and components of boilers, such as economizers, superheaters, reheaters, and, in some circumstances, feedwater heaters. Although its title is Rules for Construction of Power Boilers, its scope is somewhat broader. The Preamble to Section I...
This document provides a comprehensive description of the different processes that are required to create openings in PT slab systems. This includes a description of the required structural analysis as well as construction methods used to create openings. The most common PT system that is used for...
This Standards Publication describes constructional details, classifications, ratings, and other characteristics of temperature limit controls and control systems of the linear-sensing or spot types, which are suitable for mounting inside electric baseboard heaters for the purpose of disconnecting...
SCOPE A post-tensioned concrete court should be considered a "slab" rather than a "foundation." In other words, it is not intended to minimize deflections to protect a supported structure. ACI 318-052 does not cover the design of soil supported slabs. Values for allowable stresses and spacing of...
INTRODUCTION In many parts of the country, post-tensioned concrete slabs with unbonded tendons have become the preferred choice for floor systems in both commercial and residential buildings. The two most popular systems are one-way slabs spanning between parallel beams placed between column...
INTRODUCTION Several references are available which describe the demolition of bonded post-tensioned concrete structures (Felstead et al, 1981, Buchner et al, 1985). The National Association of Demolition Contractors (NADC. 1981) has issued a demolition safety manual for special structures...
Introduction This manual was developed to provide a comprehensive reference for the design, construction, and maintenance of free-standing, cast-in-place concrete parking structures. The emphasis of the manual is on design, construction, and maintenance practices that will ensure long-term...
