I dont understand this?! So in ETABS you cannot design slabs for required reinforcement?

..and the usual practice in USA is to place a vapor barrier directly under the slab, maybe also place an layer of granular material...

Thanx :-)

Sorry I dont understand you :-( Something on "root" function?

Root functions seems to work for this couse I can get numeric value. Anyother ideas?

One more question, and thenx for the previous answer. How to use the result you get? Im asking this becasue if I have even the simpliest equation like 2x+3=0, in Mathcad I would get -3/2 using the "solve for x". But how to use the x value (-3/2) for your further calculations?

...and you like to drink wich beer and how much? :-)

"solve block" Is that a command inside Mathcad or something else?

Hi guys! Need a little help couse Mathcad doesnt allow me to deine the integral limit as the unknown. Simple egsample: integral of "x dx" with limits "a=0 and b=5". The solution is 12.5 How to reverse the situation so that a=0, b=unknown and provide the previous result of 12.5? I want Mathcad...

Damn! :-( I thought there could be a way of exporting everything to Excel and use it there.

Hi! The title says it all. Im asking this because I would like to give my friend an sheet that I made for designing a RC section. The problem is that he doesnt have Mathcad. Can he somehow use this without the need to instal Mathcad? Thanx!

@Twinkie Understood, althou I could use a crash course @BigH I found it on Amazon but could not find and table of content I found this book also...

@Twinkie Yes to re-learn (learned long ago) the subject and design a road. Why do you say its not going to teach me the subject?

Hi! Thanx for the response. I found two interesting books: http://www.mhhe.com/engcs/civil/banks/ and http://www.amazon.com/Policy-Geometric-Design-Highways-Streets/dp/1560515082/ref=sr_1_1?ie=UTF8&qid=1378738603&sr=8-1&keywords=a+policy+on+geometric+design+of+highways+and+streets They both...

Anyone, please :-(

Hi! Can anyone recommend a good book on this subject. Horizontal aligment design, vertical aligment design, superelevation, parking places... I found few good topics on the internet but I would like to buy a good book. Thank you.

Hi! I found a very interesting topic here on slabs on grade http://anc-tbquimby01.uaa.alaska.edu/courses/ce433/Quimby/ce43310.htm Last topic coverd. Heres the direct link for download: http://anc-tbquimby01.uaa.alaska.edu/courses/ce433/Quimby/docs/2010/10CE433SlabsOnGrade.mp4

@TXStructural Thanx for the reference text. This topic seems to be more oriented towards type I&II slabs (unreinforced and slightly reinforced). Type III slabs are general raft systems where slab recives and transmits all load from superstucture to the ground. Looking at drawings (pages 40,42...

Hohie66 thanx for your response. So you are in favour for "casted over strips" solution?

@hokie66 Agree, but here the strips would be first casted. Then later, ground slabs, between the strips. Strips would basicly serve as side formwork. But here another thing that I see as a problem. Elastic settlement of strips. If the settle eg.2cm, slabs wont follow and there could be...
