This manual describes the details of the shear wall design and stress check algorithms used by the program when the user selects the ACI 318-14 design code. The various notations used in this manual are described in Section 1.1. The design is based on loading combinations specified by the user (Section 1.2). To facilitate the design process, the program provides a set of default load combinations that should satisfy requirements for the design of most building type structures.

“wind and seismic loads are the most common loads that shear walls are designed to carry.” Shear wall is a structural system composed of braced panels or shear panels to resist the effects of lateral load acting on a structure, wind and seismic loads are the most common loads that shear walls are designed to carry. Under several building codes, including the international Building Code and uniform building code, all exterior wall lines in wood or steel frame construction must be braced. Depending on the size of the building some interior walls must be braced as well.
Dear Colleagues, Please see the attached image, showing Uniform Reinforcing Pier Design details of a RC shear wall, designed using ETABS 9.7.4. In addition to providing structural details, the output displays some error messages as well. In this connection, I want to know: 1. What type of design or structural problems do these messages indicate, especially the Design Inadequacy Message? How these error messages can be avoided?
Note: It is a 2B+10-storey building, located in seismic zone 2B, and modeled as an IMRF. Material design code is ACI 318-99 and seismic design is based on UBC 97. Dear members, I am working on a 10 storied rcc factory building with one basement, where floor loads are in general 125 psf(Live).
But there are 2 warehouse in the building at ground floor & 10th floor where the Live load of stacked materials are 450psf. I have modeled it and analysed in ETABS. After analysis, seeing the floor displacement for seismic load, i am in big shock to see the pattern. The displacement pattern suddenly increased hugely & then got normal.
If the warehouse load created problem, then why it effected only Ground floor level, not the 10th floor! Please tell me how can i solve it. Asalamualaikum all, I have columns which are conflicting with the underground water tank as shown in figure. So I have decided to make underground water tank base slab as a footing for column. So I import etabs model to safe and just take uniform water load on base slab and point load from columns.
This is the residential house. The BC is 2tsf. But SAFE is showing tension on the base slab and the thickness from punching is 30'.
I believe that thickness is too high. 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. You can find the list of all the new improvements by visiting this website. Some highlights are: 1) Improved Search Features 2) Emoji Emoji support is now available in all editors. Do check out the link posted above for the complete list.
One additional announcement that I would like to make is that with reference to last forum update post (read below), @Rana and @BAZ are forum Admins now. I think it was important to do as it brings more transparency for the forum and also helps spread the responsibility. The forum belongs to the members so it never made sense for one person to be Admin, As always, feedback is much appreciated. Thanks for taking the time out to read this update. Hi guys just to discuss with you my understanding of crack widths in Environmental structures according to ACI. Normal structures - 1. ACI 318-95 based on statistical method of Gergely & Lutz 1968 limits Z based on exposure.
We are calculating crack widths here. (Normal structures) 2.
ACI 318-99 proposed limiting the spacing and removed actually calculating the width and also removed the exposure conditions. 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 224R-01 references method 1 and 2 above and 3 european codes.
The most confusing part is the table in which Nawy suggests 0.1mm crack width for water-tight structures. The whole document is for normal structures except this line.
And people are following this line and refer to this document for water tight structures. I mean its just a suggestion and by the way this method 1 is obsolete now since ACI 318-99 (see point 2 above). Water tight structures - 1. ACI 318-08 states clearly that for watertight structures ACI 350-06 codes should be used. ACI 224.4R-13 also specifically states that for watertight structures walls in section 7.4, we should use ACI 350-06. 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.
Etabs Shear Wall Design Manual
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. For normal structures: fs=0.6fy and for water tight structures fs=0.33fy. Hi I want to know the use of diaphragms in etabs. I discus many people who are use etabs but i can't get justified answer about the application of etabs. I read the Technical reference of Etabs, where they write about Diaphragms. I get two type of diaphragms (plate or shell and joint or beam). When do i use Shell diaphragms (if floor present ) 2.When do i use joint diaphragms ( grade beam level where no slab are provide) NB: Diaphragms use to transfer the lateral load to the resisting element ( frame such as column.
Beam,shear wall).SEFP Consistent Design.Pile Design.Doc No: 10-00-CD-0005.Date: Nov 21, 2017. This article is intended to cover design of piles using Ultimate Limit State (ULS) method. The use of ULS method is fairly new for geotechnical design (last decade).
The method is being used in multiple countries now (Canada, Australia etc). The following items shall be discussed: Overview Geotechnical Design of Piles (Compression Loads, Tension Loads and Lateral Loads) Structural Design of Piles (Covering both Concrete and Steel) Connection of Pile with the foundation (Covering both Concrete and Steel) Pile Group Settlement Things to consider 1. Overview Piles provide a suitable load path to transfer super-structure loads to foundation where shallow foundation are not suitable - this can be due to a number of reasons like existing space constraints or suitable soil strata is not present immediately below structure. Other uses can be to meet design requirements like to have reduced settlement etc. This article shall cover the use of straight shaft cast-in-place concrete piles and straight shaft driven steel pipe piles.
There are a number of additional piles types like belled concrete piles, precast concrete piles, screw / helical steel piles etc but the discussion to choose a suitable pile type is not in the intended scope of this article. The article is intended to discuss design requirements for straight shaft piles only (both concrete and steel). The aforementioned topic about pile selection is a very diverse subject and requires a separate discussion on its own. Click on the link to read the full article.
Dear all, I am trying to design shearwalls through ETABS with temperature load applied over shell. At various location, spandral section fails in Shear due to temperature and piers (sometime in shear, mostly in flexure). 2017 honda accord sport v6. (See Attached Image) Certainly all the problem in Shearwalls are due to temperature. I don't want to increase cross section of spandral or pier at some location just due to temperature load case as it will appears non-uniform with rest of the wall. I have seen stiffness modifier affect distribution of forces and also rigid/semi rigid daiphragm assumption. Can anybody guide how to properly design the shear wall with temperature load applied in ETABS or share any similar experience.
Thanks in Advance.
