Topic 1: ACI 318-19 "Building Code Requirements for Structural Concrete"

The Dubai Municipality and the American Concrete Institute recently signed a memorandum of understanding to encourage cooperation in areas of codes and standards, research, technical committees, publications, and other related activities. With the Gulf countries experiencing rapid construction growth, the use of ACI 318 building code has been increasing in this region and worldwide, with more than 22 countries currently base their national building codes on all or part of ACI 318. The objective of this seminar is to provide design professionals in UAE with the latest development with the ACI 318-19 building code.

The presentation will cover the reorganization approach and philosophy for the new ACI 318-19 code to be published this year. It will discuss the new code’s outline and the main revisions to code provisions and chapters, to give attendees insight into the background that lead to the code reorganization efforts. The intent of the reorganization efforts is to make the new code easier to use by design professionals and allows design professionals to quickly determine the design requirements for different types of structural elements.

The presentation will also cover the main code sections and recent changes to the code such as: size effect in shear elements, revised requirements for development length, and the inclusion of deep foundation.

As a recognized leader in advancing concrete technologies and standards, the American Concrete Institute is committed to disseminating knowledge to ensure customers are equipped to sustainably address the needs of a changing world.


About the Speaker

Khaled Nahlawi, PhD, PE is a Senior Engineer at the American Concrete Institute. His role at ACI is to provide technical and administrative support to ACI’s Technical Committees and communicate the work of these committees to other Standard Developing Organizations and Regulatory Agencies. He received his PhD from the University of Michigan. Khaled has over 20 years of experience in the design and strengthening of structures. He joined ACI in 2009 as a senior engineer and has supported, among other duties, in the re-organization effort of 318. He is a registered engineer in California and Michigan.

Topic 2: ACI 562-16 "Code Requirements for Assessment, Repair and Rehabilitation of Existing Concrete Structures and Commentary"

The growth of the concrete repair industry globally has resulted in the need for significant improvements in material performance, repair design process and practice, installation procedures, contracting processes, quality control/quality assurance procedures, and education.

The ACI 562-16 code was developed to provide design professionals with a performance-based code document for the assessment of damaged and deteriorated concrete structures and the development of repair and rehabilitation strategies.

The seminar will cover the philosophy of the new ACI 562-16 “Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary”, its content, and some of the key requirements regarding evaluation of existing structures, design of the repairs, and quality control. It also included repair project examples to illustrate the use of ACI 562-16. The focus of this topic will be on increasing participants’ knowledge of requirements for repair process of concrete structures.


About the Speaker

Tarek Alkhrdaji, PhD, PE, is Vice President of Engineering with Structural Technologies. Dr. Alkhrdaji has experience in structural repair and strengthening and full-scale load testing of concrete structures. He has been involved in more than 800 projects involving structural repair and strengthening – several of which received awards from The American Concrete Institute (ACI), the Post-Tensioning Institute (PTI), and the International Concrete Repair Institute (ICRI). Tarek has written more than 40 papers and articles on strengthening of structures including buildings, bridges, silos, tanks and concrete pipes.

Dr. Alkhrdaji is an active member of the America Concrete Institute ACI Committees 216 (Fire rating), 437 (Strength Evaluation), and is a voting member of ACI 562 (Repair Code). He is the past Chair of ACI 440F (FRP Strengthening) and is currently chairing the International Concrete Repair Institute (ICRI) committee 330 (Strengthening and Stabilization).

Topic 3: Strengthening of Concrete Structures

Although the analysis and upgrade of concrete structures is somewhat of a “scientific art” that has been practiced for many years it has evolved into a complex science that requires a blend of engineering, material science and construction perspectives.

Strengthening projects may utilize traditional materials such as conventional cement-based and steel materials as well as advanced composite materials (FRP’s) that are commonly used for aerospace applications. The techniques used to design and install these materials for upgrade applications are not common to the engineering and general construction industry which can make strengthening projects even more challenging and complex than new construction.

There are many factors that create the need for strengthening. They include construction and design errors, increase in live load, new code requirements, low concrete strength, voids created during concrete placement, new penetrations and prevention of progressive collapse from blast loads.

Topic 4: Techniques to repair, replace, modify and investigate existing bonded post-tensioning tendons

Prestressed concrete construction has been used for more than 60 years; however, there are no specific guidelines on how to repair or modify bonded post-tensioning (PT) tendons that have prestressing strands permanently grouted inside smooth or corrugated ducts. Industry organizations like the Post-Tensioning Institute and Building Codes only address PT tendons in new construction leaving it up to industry professionals on how to design and fabricate specialty hardware and equipment required to perform this type of work.

The purpose of this presentation is to share practical knowledge and state of the art techniques used to ensure precompression and ultimate capacity is restored/maintained when the PT is affected from deterioration, yielding from high temperatures, damaged from
impact, ducts with grout voids or severed strands from cutting/coring. Additionally, the presentation will give consultants rules of thumb for design to make sure they avoid other challenges such as restraint cracking, stress reversal or accelerated corrosion when modifying existing PT structures.

These techniques will be illustrated through case studies from projects in the UAE and USA.
