BACKFILL FOR SUBSURFACE STRUCTURES

FOREWORD

The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD(AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States is also governed by Status of forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA) Therefore, the acquisition team must ensure compliance with the more stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable.

UFC are living documents and will be periodically reviewed, updated, and made available to sers as part of the Services’ responsibility for providing technical criteria for military construction. Headquarters, U.S. Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC), and Air Force Civil Engineer Support Agency (AFCESA) are responsible for administration of the UFC system. Defense agencies should contact the preparing service for document interpretation and improvements. Technical content of UFC is the responsibility of the cognizant DoD working group. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: Criteria Change Request (CCR). The form is also accessible from the Internet sites listed below.

UFC are effective upon issuance and are distributed only in electronic media from the following source:

GROUND ANCHORS AND ANCHORED SYSTEMS

Abstract:

This document presents state-of-the-practice information on the design and installation of cementgrouted ground anchors and anchored systems for highway applications. The anchored systems discussed include flexible anchored walls, slopes supported using ground anchors, landslide stabilization systems, and structures that incorporate tiedown anchors. This document draws extensively from the FHWA-DP-68-IR (1988) design manual in describing issues such as subsurface investigation and laboratory testing, basic anchoring principles, ground anchor load testing, and inspection of construction materials and methods used for anchored systems. This document provides detailed information on design analyses for ground anchored systems. Topics discussed include selection of design earth pressures, ground anchor design, design of corrosion protection system for ground anchors, design of wall components to resist lateral and vertical loads, evaluation of overall anchored system stability, and seismic design of anchored systems. Also included in the document are two detailed design examples and technical specifications for ground anchors and for anchored walls.

Seismic Structural Considerations for the Stem and Base of Retaining Walls Subjected to Earthquake Ground Motions

ABSTRACT:

Cantilever retaining walls can respond externally to earthquake ground motions by sliding or by rotating, or internally by stem wall yielding. The type of response that will have the greatest impact on post-earthquake performance will likely depend on restraint conditions at the base of the wall. Walls founded on soil without an invert slab are most likely to dissipate the inertial energy imposed by earthquake ground motions by sliding. This may also be true for walls founded on fissured or fractured rock. Walls founded on soil or on fissured or fractured rock and prevented by an invert slab from moving laterally are more likely to tip (i.e., rotate) than to slide during a major earthquake event. Walls founded on competent rock without significant joints, faults, or bedding planes and prevented by a strong bond at
the rock-footing interface from either translating or rotating are likely to dissipate energy through plastic yielding in the stem wall. All three responses can leave the retaining wall in a permanently displaced condition.

The purpose of this report is to provide methodologies for conducting a performance-based earthquake evaluation related to plastic yielding in the stem wall. The methodologies include evaluation of brittle or force-controlled actions and the evaluation of ductile or deformation-controlled actions. The later evaluation provides estimates of permanent (residual) displacement for walls dominated by a stem wall yielding response.

Performance-based evaluation methodologies are demonstrated with respect to a wall designed to current Corps ultimate strength design criteria and with respect to an older retaining wall designed to working stress design criteria. Lap splice deficiencies related to older walls are discussed and performance-based evaluation techniques proposed.

At present the Corps computer program CWRotate is able to estimate permanent displacements associated with a sliding response and a rotational response. An enhancement is proposed to provide estimates of permanent (residual) displacement for walls dominated by stem wall yielding.

Seismic Design, Assessment and Retrofitting of Concrete Buildings

Seismic Design, Assessment and Retrofitting of Concrete Buildings: based on EN-Eurocode 8
Publisher: Springer | ISBN: 1402098413 | edition 2009 | File type: PDF | 767 pages | 13 mb

Reflecting the historic first European seismic code, this professional book focuses on seismic design, assessment and retrofitting of concrete buildings, with thorough reference to, and application of, EN-Eurocode 8.

Following the publication of EN-Eurocode 8 in 2004-05, 30 countries are now introducing this European standard for seismic design, for application in parallel with existing national standards (till March 2010) and exclusively after that. Eurocode 8 is also expected to influence standards in countries outside Europe, or at the least, to be applied there for important facilities. Owing to the increasing awareness of the threat posed by existing buildings substandard and deficient buildings and the lack of national or international standards for assessment and retrofitting, its impact in that field is expected to be major.

Post-Tensioned Concrete Floors

Post-Tensioned Concrete Floors By Martin Williams, Sami Khan
Publisher: Laxton's 1995 | 256 Pages | ISBN: 0750616814 | File type: PDF | 16 mb

Post-tensioning is the most versatile form of pre stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.

The Foundation Engineering Handbook

Manjriker Gunaratne, "The Foundation Engineering Handbook"
CRC Press | January 2006 | ISBN: 020348441X | File type: PDF | 625 pages | 7 mb

Great strides have been made in the art of foundation design during the last two decades. In situ testing, site improvement techniques, the use of geogrids in the design of retaining walls, modified ACI codes, and ground deformation modeling using finite elements are but a few of the developments that have significantly advanced foundation engineering in recent years. What has been lacking, however, is a comprehensive reference for foundation engineers that incorporates these state-of-the-art concepts and techniques.

The Foundation Engineering Handbook fills that void. It presents both classical and state-of-the-art design and analysis techniques for earthen structures, and covers basic soil mechanics and soil and groundwater modeling concepts along with the latest research results. It addresses isolated and shallow footings, retaining structures, and modern methods of pile construction monitoring, as well as stability analysis and ground improvement methods. The handbook also covers reliability-based design and LRFD (Load Resistance Factor Design)-concepts not addressed in most foundation engineering texts. Easy-to-follow numerical design examples illustrate each technique. Along with its unique, comprehensive coverage, the clear, concise discussions and logical organization of The Foundation Engineering Handbook make it the one quick reference every practitioner and student in the field needs.

Airport Design and Operation

Antonin Kazda, "Airport Design and Operation"
Elsevier | 2007 | 538 Pages | ISBN: 0080451047 | File type: PDF | 16 mb

The annual number of airline passengers has continued to increase in the past decade, putting great strain on the airports. Increasing volumes of passengers and freight will continue making demands for expansion of airport facilities and construction of new airports. Traditionally airport design and airport operation have been treated separately, yet they are closely related and influence each other. Poor design adversely affects operation; sound understanding of operation is needed to enable good design. The aim of this book is to present a new and integrated approach to the two.

This second edition includes some important changes in the international regulations covering design and operations. It reflects the greater attention being given to security, safety and the environment, together with changes in the technology and the way the air transport industry operates.

New sections on collaborative decision making and low visibility operations strengthen the operational character of this book. Two completely new chapters have been added covering the topical problems of cargo and radio navigation aids and the chapter on passenger terminals has been enhanced considerably.

Construction Waterproofing Handbook

Diskripsi :

Prinsip-prinsip dasar waterproofing disajikan dalam buku ini dan yang lebih banyak disajikan adalah panduan dalam merancang, membangun dan memelihara struktur agar terhindar dan tahan air.

Bukti-bukti yang banyak ditemukan dalam kegagalan konstruksi dan dan kebocoran adalah akibat kaidah atau prinsip yang tidak diperhatikan, sehingga terjadi kebocoran dan sehingga merusak konstruksi.

Waterproofing akhirnya didefinisikan bukan sebagai sistem individual tetapi sebagai sebuah proses konstruksi, yang melibatkan semua komponen cladding eksterior bangunan-bukan sebagai tanggung jawab satu subkontraktor individu waterproofer, tetapi seluruh tim konstruksi, dari mulai perancanaan (perencana) sampai kepada pelaksanaan (kontraktor) dan juga seluruh sub kontraktor dan pemasok material.
