Seismic Behaviour and Retrofit of Historic Masonry Minaret
Author: Prof. Ahmet Murat Turk, Ph.D. (Civ.Eng.) Istanbul Kultur University Civil Engineering Department.Cumhur Cosgun, B.Sc. (Civ.Eng.) Istanbul Kultur University Civil Engineering Department | Size: 0.73 MB | Format:PDF | Quality:Unspecified | Year: 2012 | pages: 07
The dynamic behaviour of block masonry minaret of a historical mosque in Istanbul is analyzed, and a seismic retrofit method is proposed. Due to high seismicity of the region, a 3D finite element model is used to determine lateral displacements and
failure modes under seismic load. The analyses show that the highest damage usually occurs at the base and the lower part of the minaret, and that lateral behaviour can be
improved by strengthening these sections with fiber reinforced polymer (FRP) sheets. The results obtained are promising in terms of seismic protection.

The “Residential Code Requirements for Structural Concrete” cover the design and construction of cast-in-place concrete for one- and two-family dwellings and multiple single-family dwellings (townhouses), and their accessory structures.
Among the subjects covered are the design and construction requirements for plain and reinforced concrete footings, foundation walls, and slabs-on-ground, and requirements for concrete, reinforcement, forms, and other related materials.
The quality and testing of materials discussed in this document are covered by reference to the appropriate ASTM standards.
The Code is written to allow for reference by adoption in a general building code without changing its language. Background details or suggestions for carrying out the requirements or intent of the Code are provided in the commentary. The commentary discusses some of the considerations of the committee in developing the Code with emphasis given to the explanation of provisions that may be unfamiliar to code users or where significant departure exists from other concrete codes. Commentary provisions begin with an “R,” such as “R.1.1.1,” and commentary text is shown in italics.
Relevant resource documents are cited for the user desiring more detailed study of individual issues.

This publication contains a comprehensive summary of the seismic detailing requirements contained in Chapter 21 of Building Code Requirements for Structural Concrete (318-05) and Commentary (318R-05), which is adopted by reference in the 2006 International Building Code.
Numerous tables and figures explain and illustrate the provisions for the following components in buildings located in regions of moderate and high seismic risk:
- Flexural members of special moment frames
- Special moment frame members subjected to bending and axial load
- Joints of special moment frames
- Special reinforced concrete structural walls and coupling beams
- Structural diaphragms and trusses
- Foundations
- Frame members not proportioned to resist forces induced by earthquake motions
-Intermediate moment frames.

ACI 369R-11 Guide for Seismic Rehabilitation of Existing Concrete Frame Buildings and Commentary
Author: ACI Committee 369 | Size: 29.76 MB | Format:Image PDF | Quality:Unspecified | Publisher: American Concrete Institute (ACI) | Year: 2011 | pages: 36 | ISBN: 9780870314193
This guide, which was developed based on the format and content of ASCE/SEI 41-06, Chapter 6.0, “Concrete,” describes methods for estimating the seismic performance of both existing and new concrete components in an existing building. The guide is intended to be used with the analysis procedures and Rehabilitation Objectives established in ASCE/SEI 41-06 for the Systematic Rehabilitation Method. The guide provides recommendations for modeling parameters and acceptance criteria for linear and nonlinear analysis of beams, columns, joints, and slab-column connections of concrete buildings and the procedures for obtaining material properties necessary for seismic rehabilitation design.

ACI 543R-12 Recommendations for Design, Manufacture, & Installation of Concrete Piles
Author: ACI Committee 543 | Size: 66.68 MB | Format:Image PDF | Quality:Unspecified | Publisher: American Concrete Institute (ACI) | Year: 2012 | pages: 68 | ISBN: 9780870317590
Piles are slender structural elements installed in the ground to support a load or compact the soil. They are made of several materials or combinations of materials and are installed by impact driving, jacking, vibrating, jetting, drilling, grouting, or combinations of these techniques. Piles are difficult to summarize and classify because there are many types, and new types are still being developed. This report covers only the types of piles currently used in North American construction projects. A pile type can be assigned a wide variety of names or classifications by various agencies, codes, technical groups, and in various geographical regions. No attempt is made herein to reconcile the wide variety of names used with a given pile type.
