Conventional Steel & Post-Tensioned Reinforced Foundations
Webinars are conducted on a platform called Go-to-Webinar. Instructions and
login information will be provided in an access email sent closer to the date of the webinar.
View system requirements here.
All attendees must log-on through their own email – attendees may not watch
together if they wish to obtain CE credit. HalfMoon Education Inc. must be able to prove
attendance if either the attendee or HalfMoon Education Inc. is audited.

WRI Foundation Design Calculations
Tuesday, May 17, 2016, 2:30 – 4:30 PM EDT
Calculate applied moment vs. reduced moment capacity – positive moment direction
Calculate applied moment vs. reduced moment capacity – negative moment direction
Calculate deflection – positive moment direction
Calculate shear stresses – negative moment direction
PTI 3 Foundation Design Calculation
Wednesday, May 18, 2016, 12:00 – 2:00 PM EDT
Type I, II, III and IV foundations – definitions
Select rectangles and trial section
Calculate applied service moment edge-lift or center lift conditions
Calculate flexural concrete stresses caused by the applied service moments
and compare them to the allowable flexural concrete stresses
Calculate the minimum required foundation stiffness and compare with the actual stiffness
Calculate the applied service shear force and shear stress in the assumed
sections and compare the applied shear stress with the allowable shear stress
PTI 3 and WRI computer design example
• Input data into PTI slab and design post-tensioned ribbed foundation
• Input data into WRI excel spreadsheet and design conventionally-reinforced foundation

Christopher S. Copeland P.E.
CEO & Managing Partner, Copeland Engineering, LLC, B.S. degree in Civil Engineering from the University of Texas at Austin
Mr. Copeland received his Bachelor of Science degree in Civil Engineering from the University of Texas at Austin in 1995. Mr. Copeland has been involved in more than 250,000 residential projects and is the CEO and Managing Partner of Copeland Engineering, LLC. During his 20 years in the engineering field, he has worked for large national volume builders, small builders, remodeling contractors, developers and high end custom builders. Through this process he has become an expert in homeowner and residential structural behavior on expansive clays in Austin, Dallas, Houston, Waco / Temple / Killeen and the San Antonio areas. Working with such volume he also became an expert at the repair process for foundations and has been through the builder warranty, insurance warranty, mediation and arbitration processes. There is no doubt that the industry of foundation design on expansive clay comes with risk and Mr. Copeland has experienced and come out successful on many lawsuit claims, audits and even the engineering complaint process. Additionally, as the industry has grown Mr. Copeland has grown with it and is also an expert in wood framing design, main wind force resisting system design, components and cladding design and going even further to have successfully completed two audits from the State of Texas via the Texas Department of Insurance. Mr. Copeland is a member of American Society of Civil Engineers, Texas Department of Insurance Windstorm Certified, American Concrete Institute and many other professional organizations.
