This document presents information on precast modular block retaining walls called Stone Strong walls. It discusses the concept, components, design theory, and construction details of the Stone Strong system. It also provides examples of innovative applications of Stone Strong walls, including integrated structures, bridge abutments, pipe penetrations, and hybrid applications. The document is intended to showcase the versatility and engineered design of Stone Strong precast modular retaining walls.
Bridge-Plate & Multi-Plate Applications and Case Studies (Ron Prychitko, P.Eng.)Communications Branding
Ron Prychitko, P.Eng. & Randy McDonald, P.Eng. will provide a complete overview of Bridge-Plate and Multi-Plate applications in Canada. Please join them for a review of engineering, construction, and performance considerations in various applications. This webinar includes case examples for bridges, culverts, stream enclosures, mine portals, road and rail grade separations, pedestrian tunnels and more.
Join Jim McKay & Slavek Piotrowski for an introduction to ARCIS – the world’s first ultra-thin, lightweight prestressed architectural precast panel.
The presenters will begin by reviewing current architectural precast concrete solutions, then introduce the ARCIS product line and its unique attributes. A brief overview of how the technology works to produce a strong but thin and light panel and a complete overview of architectural applications for ARCIS will follow.
The session will conclude with installation procedures, design considerations and other uses for the Arcis technology.
ARCIS has been used in the full spectrum of projects from residential high-rise, low-rise, retail storefronts, hospitals, malls, universities, public buildings, stadiums and marinas.
Applications include:
- Architectural facades & rain screens
- Ventilated facades & sunscreens
- Décor, accent walls and interior accents
- Louvers and fins
- Decking
- Stair Treads
Utah SAMPE Chapter, Thursday, March 22nd, 2001.
A Powerpoint presentation given to the Utah SAMPE Chapter on the development of Trek's OCLV line of bicycles, which received huge mass market TV exposure when ridden to eight victories in the world's most viewed athletic event, the Tour de France. Carbon fibre composite bicycle frames have developed into a high volume consumer applications over the past decade, and are now dominate on high-end racing bikes.Ron Nelson of ClosedMold Composites, primary inventor of the Trek OCLV bicycle frame, explains how the integrated development of a manufacturing process and frame design lead to a successful commercial product line.Lance Armstrong has ridden Trek’s composite road bike to victory in four Tour de France events. This presentation will recap developments in all-composite bicycle frames from the monocoque-fiberglass Bowden Spacelander in 1960, through Lance Armstrong's 1999 Tour de France victory on a stock (1991 Technology) Trek OCLV Frame, to new, lower-cost and higher-performance technologies for the coming decade. The speaker, Ron Nelson, invented, developed, and designed Trek Bicycle Company's OCLV line of road and mountain bicycles and manufacturing process. This included marketing the design and manufacturing concept to the customer (Trek), negotiation of a long term licensing contract, and product/process design and development including structural testing and production setup. This product line was a $6MM business for Trek in first model year (1992), and grew to roughly $45MM by the fourth production year.
Ron Nelson is also inventor of closed-mold carbon composite products that won gold medals in the last five Olympics and several other non-Olympic sporting good products, in addition to the last two Tour de France wins. Ron has been personally interested in the technical changes in bicycle construction since the early 70's, and recently retired as President and Co-Founder of Radius Engineering, Inc.

18. HITEC Evaluation
What DOT can take from the report:
- Evidence of conformance w/ AASHTO methodologies
- Rigorous technical review
- Viable alternative to traditional retaining systems
28. Trial Wedge Method
Well established methodology
to resolve complex loading
conditions & geometry
Not commonly used due to
computational effort
More accurate assessment of
actual load applied outside of
Coulomb contributory area
Variation of Coulomb
technique
Still consistent with AASHTO
and other standards
