Der erste und zweite Teil dieser "Vorlesungen über Massivbau" behandeln die Bemessung im Stahlbetonbau. Der dritte Teil ist den Grundlagen des Bewehrens gewidmet. Für die richtige Führung der Bewehrungen muß man den Verlauf der Zugkräfte im Inneren der Stahlbetontragwerke kennen. Die Bewehrungen müssen zur Gewährleistung der Trag- und der Gebrauchsfähigkeit der Stahlbetontragwerke dem Verlauf der Zugkräfte möglichst genau entsprechen. Diese Forderung kann aus fertigungstechnischen Gründen meist nicht voll erfüllt werden. Deshalb muß der Ingenieur, gestützt auf Versuchsergebnisse und Erfahrung, Lösun­ gen anstreben, die neben der unabdingbaren Standsicherheit kleinstmögliche Rißbreiten ge­ währleisten. Dazu muß er die Gesetze der Verbundwirkung und der Verankerungen kennen und wissen, welche Einflüsse die Größe der Stabdurchmesser , die Abstände der Bewehrungs­ stäbe und die Abweichung ihrer Richtung von der Richtung der Hauptzugspannungen auf die Rißbreiten haben. Für die Bauausführung muß darüber hinaus die Herstellung und das Zusammenfügen der Be­ wehrungen und Bewehrungskörbe im Auge behalten werden, wobei es heute darauf ankommt, nicht unbedingt das Minimum an Stahlgewicht zu erreichen, sondern Arbeitslöhne zu sparen. Gerade die fertigungstechnischen Überlegungen zur Verminderung der Lohnkosten haben in den letzten Jahren die Art der Bewehrungen stark beeinflußt. Diese Entwicklung ist noch im Gange. Die hier gezeigten Bewehrungen tragen dieser Entwicklung wohl schon Rechnung, es ist jedoch zu erwarten, daß die Rationalisierung der Bewehrungen in den nächsten Jahren noch manche Veränderungen besonders im Hinblick auf fabrikmäßig vorgefertigte Bewehrungsteile bringen wird.

Not linen
These aren’t linen, these are microfiber shorts. Fabric feels very cheap.

True To Size
These shorts fit true to size and are so comfortable. They have a drawstring waist, so you can adjust them for the best fit and wide legs. They are 55% linen and 45% cotton so they keep you feeling cool. The classic colors go with nearly any other colors or designs, making them stretch your wardrobe potential and saving you money. They were extremely wrinkled upon arrival, so I used my fabric steamer, and within 5 min they looked perfect. I love these shorts and wear them all the time!

Cute 2-pack pair of shorts
Color: Black, White, Size: Medium, Color: Black, White, Size: Medium
Cute shorts that have pockets and fit true to size. I love that they come in a pack of two as well. The black ones are my favorite and I feel like the fabric is a little softer on the black pair. The white ones are a little thinner than I would like. I was wearing an olive green colored underwear underneath them in the pictures in my review and though you can’t see them much, I do feel like they were slightly visible. The white pair also had a lot of loose strings on them which made me think the quality might not be as good as with the black pair. They washed easily and I hung them up to dry them because they smelled kind of funny when they arrived.

Good value for 2 shorts
These come vacuum sealed and have crazy wrinkles... so be prepared to do some ironing. I ordered the Mediums as I am a 6-8. The black pair feels a bit smaller than the beige pair... with both feeling tighter than I like for comfort. The look nice on, but feel like it constricts my belly a bit too much. Overall a nice basic set of shorts, perhaps size up for a more comfortable fit.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
