I discus many people who are use etabs but i can't get justified answer about the application of etabs. Hi I want to know the use of diaphragms in etabs. For normal structures: fs=0.6fy and for water tight structures fs=0.33fy

To sum it up, Philosophy of crack width control is not to calculate probable crack widths but to limit the max stress in steel bars. ACI 350-06 for water tight structures does not recommend calculating a number for crack width but rather limiting max steel stress in bars to be 20k ksi or fs=0.33fy for normal conditions. ACI 318-08 states clearly that for watertight structures ACI 350-06 codes should be used.ДЄCI 224.4R-13 also specifically states that for watertight structures walls in section 7.4, we should use ACI 350-06. I mean its just a suggestion and by the way this method 1 is obsolete now since ACI 318-99 (see point 2 above). And people are following this line and refer to this document for water tight structures. The whole document is for normal structures except this line. The most confusing part is the table in which Nawy suggests 0.1mm crack width for water-tight structures. ACI 224R-01 references method 1 and 2 above and 3 european codes. For example for beams and one-way slabs s (in) = 540/fs -2.5cc or in other words limiting the fs=0.6fy (For normal structures) 3. ACI 318-99 proposed limiting the spacing and removed actually calculating the width and also removed the exposure conditions. ACI 318-95 based on statistical method of Gergely & Lutz 1968 limits Z based on exposure. Hi guys just to discuss with you my understanding of crack widths in Environmental structures according to ACI. Thanks for taking the time out to read this update. The forum belongs to the members so it never made sense for one person to be Admin, As always, feedback is much appreciated. I think it was important to do as it brings more transparency for the forum and also helps spread the responsibility.

One additional announcement that I would like to make is that with reference to last forum update post (read below), forum Admins now. Do check out the link posted above for the complete list. Some highlights are: 1) Improved Search Features 2) Emoji Emoji supportВ is now available in all editors. You can find the list of all the new improvements by visiting this website. What can be the error? Is this approach is correct for design base slab of ugwt to carry load of two edge columns? Dear All, The forum has been updated today with a lot new features. But SAFE is showing tension on the base slab and the thickness from punching is 30'. So I import etabs model to safe and just take uniform water load on base slab and point load from columns. So I have decided to make underground water tank base slab as a footing for column. A Soundfont file, or Soundfont 'bank', contains one or more sampled audio waveforms (or 'samples'), which can be re-synthesized at different pitches and dynamic levels. Each sampled waveform may be associated with one or more ranges of pitches and dynamics.

Soundfont technology is akin to software sampling. Asalamualaikum all, I have columns which are conflicting with the underground water tank as shown in figure. If the warehouse load createdВ problem, then why it effected only Ground floor level, not the 10th floor! Please tell me how can i solve it. The displacement pattern suddenly increased hugely & then got normal. After analysis, seeing the floor displacement for seismic load, i am in big shock to see the pattern. But there are 2 warehouse in the building at ground floor & 10th floor where the Live load of stacked materials are 450psf.
