Variation of mechanical properties in oak boards and its effect on glued laminated timber
The renewable material wood and hereof derived structural engineered wood products (EWPs) is widely acknowledged as being the major pillar of sustainable building constructions. Due to an increasing availability and high mechanical performance the wood resource hardwoods has been gaining traction for the use in EWPs, typically dominated by softwoods. Wood, being a naturally grown material, exhibits a pronounced variation in its mechanical properties, presenting marked differences not only between species, but also between individual trees and locally throughout the stem of each tree. Glued laminated timber (GLT) reduces this variation by vertical glue-stacking previously finger-jointed boards to form a highly homogenized wooden beam. This configuration reduces considerably the variation of the observed global mechanical properties of GLT with respect to the individual boards. However, the rather complex material composition of GLT prohibits the derivation of an analytical relation between local (e.g. intra board and finger-joints) and global properties, thus numerical approaches need to be applied. This work addresses the need for an improved understanding and modeling approach of the variability of stiffness and strength along and between boards, and the resulting impact on the size-effect of GLT made of oak.- Shop: buecher

Home Front: Sparky Hemingway, Book 1 , Hörbuch, Digital, ungekürzt, 414min
When aging, balding, copy editor Ernest "Sparky" Hemingway (no relation) gets a call from the daughter of his Vietnam buddy George Washington (also no relation), he is faced with a choice. He can head out to Minneapolis to help her out of a jam or hang up the phone - and this phone call has the potential to turn Sparky's life upside down. He's managed to erect a pretty effective cocoon around himself over the last few years, and no amount of aggravation (or thoughts about his long-gone ex-wife) can get through his very carefully nurtured shell. He's very comfortable living (well, maybe just existing) in the little North Dakota town of Hardwoods, filled with its decidedly odd folks who just do what they have to in order to get along, where everybody knows everybody else's secret but pretends they don't. He's left alone, and that's the way Sparky likes it. But you don't walk away from a promise. Especially when that promise was made to somebody who pulled your butt out of more unfriendly and friendly fire than a hailstorm of June bugs. You don't ask, you just do. His fellow vet buddy Doc Holiday (you guessed it, no relation) meets him in Minneapolis and tosses him a .45, which comes in handy when they run into a hard time with some gang-bangers who are after the girl in question. They rescue Washington's teenage daughter, Tenisha, and Doc and Sparky split up, Sparky taking Tenisha and her cat back to his place. Between dealing with the aforementioned gang-bangers, the Minneapolis police, who are hassling Sparky, Doc's brain tumor, and the mostly white town Sparky lives in taking umbrage at the color of Tenisha's skin - not to mention having to haul a four-month-pregnant neighbor and her baby to his house for safety during a blizzard - Sparky thinks he's handling himself pretty well. And then things start to get weird. ungekürzt. Language: English. Narrator: Tom Richards. Audio sample: https://samples.audible.de/bk/adbl/007138/bk_adbl_007138_sample.mp3.
