Seminar lecture notes

 


Who should attend?   

Consulting engineering firms, government agencies including municipalities, material suppliers, testing agencies, academia, and contractors.

 

 


Seminar Topics   

    ACI published a Standard for design of environmental engineering concrete structures, specifically liquid-containing structures (LCS). The main objective of this intensive seminar will be to familiarize the attendees with the requirements for seismic design of LCS and improve the state of practice. With the use of several design examples, LCS will be designed based on the current code approach.

Faculty   

Two of the following will be your instructors:

Carl A. Gentry, MSc, PE, Chief Structural Engineer, Carollo Engineers, Walnut Creek, CA. Mr. Gentry obtained his B.Sc. and M.Sc. from Washington State University. He has over 30 years of experience designing structures for wastewater treatment plants, water treatment plants, pump stations, pipe lines, bridges, and related facilities that were mainly located in high seismic areas on the west coast. Many of the projects designed are located on soft soil sites and sites where soil liquefaction has been an issue. Mr. Gentry has performed seismic studies and seismic retrofits for wastewater treatment plants, water treatment plants, and pump stations. He has inspected earthquake damage for a number of earthquakes including the Coalinga, El Centro, Lander, Loma Prieta, Mendocino, Northridge, and Whittier earthquakes in California.

Charles S. Hanskat, ME, FACI, FASCE, PE, Principal Engineer, Skokie, IL. He is a licensed professional engineer in nineteen states, and has been involved in the design, construction, and evaluation of environmental concrete structures for over 30 years. He serves on the ACI Board, Marketing and CLC Committees, as well as ACI 301, ACI 506 and several TAC Committees. He is a current member and past chair of ACI 350, Environmental Engineering Concrete Structures. Hanskat is also a member of ACI 371, ACI 372, ACI 373 and ACI 376, all dealing with circular concrete liquid-containing tanks. He has been active in the American Society of Civil Engineers, National Society of Professional Engineers, and the Florida Engineering Society since engineering school. He has served as state president of FES and national director of NSPE. He has received several prestigious awards.

M. Reza Kianoush, PhD, PE, Professor of Civil Engineering, Ryerson University, Toronto, Ontario, Canada. He has over 20 years experience in design, research and teaching of structures. He has specific expertise in finite element analysis and design of reinforced concrete structures. He has extensive experience in vibration analysis, earthquake analysis and design of concrete structures. His research interests include analytical modeling of reinforced concrete structures and the development of performance-based design methodologies. He has special interest and considerable experience on the behavior and design of concrete liquid containing structures. He has been involved in seismic code development and the implementation of research results in engineering practice.

Ramon E. Lucero, MS, PE, Vice-President Engineering and Computer Operations, at DYK Incorporated, El Cajon, CA. Mr. Lucero possesses extensive experience in design, analysis, and evaluation of environmental concrete structures. He has worked on water and wastewater projects related to seismic assessment and rehabilitation, structural analysis and evaluation, as well as value engineering. He is a Member of ACI 350, Environmental Engineering Concrete Structures; Chair of subcommittee “E” (Pre-cast/Pre-stressed) of ACI 350, and is a member/chair of other ACI and AWWA committees.

Javeed A. Munshi, PhD is principal engineer and concrete design specialist with Bechtel Power in Frederick, MD. He has about 20 years of experience in analysis, design and evaluation of concrete structures. He has worked on buildings, bridges, underground structures (tunnels), environmental concrete structures and heavy industrial fossil and nuclear power structures. He is widely published and has conducted concrete design seminars and training for the American Concrete Institute (ACI), the Portland Cement Association (PCA), and the Concrete Reinforcing Steel Institute (CRSI). He has served as an expert for peer review of many projects. He is member of several ACI Committees including ACI 350 – Environmental Engineering Concrete Structures, ACI 437 – Strength Evaluation of Existing Concrete Structures, ACI 374 – Performance-Based Seismic Design of Concrete and ACI 314 – Simplified Design of Concrete Structures.
