I saw in the video time 23.04 the anchor bolt 4 does not take any forces and its Utt around 0. Is there anyway to distribute the shear force to all anchors? Pls clarify this.
Hello Seran, the bolt A4 is not loaded by tension, thats why Utt (utilization in tension) is 0. Shear utilization Uts is also 0, because there is no shear, anchors are loaded by moment only, shear is transfered via friction (the lower part of the base plate is pushed into the concrete by big moment).

Hi, during calculation stage, the Anchor bolts are not getting designed. What could be the issue? How to check whether the modelled anchor bolts are pre installed or post installed?
Hello, you can reach to our technical support and send you model for investigation, maybe there are some limitations in the code checks of chosen standard www.ideastatica.com/support-center/how-to-create-a-new-support-case the anchors are by default post installed - for pre installed you can turn off the concrete breakout in the code setup www.ideastatica.com/support-center/concrete-cone-area-of-single-anchor-and-group-of-anchors

Is it possible to incorporate J bolts as anchors in IDEA StatiCa's anchorage module? If so, how can I introduce and specify the properties of these J bolts, including dimensions, material, and connection details? Additionally, what considerations should be taken into account in terms of model geometry and loading conditions?
Hello, no, only straight anchors are supported with washer plates www.ideastatica.com/support-center/limitations-to-checks-of-anchors materials can be defined custom www.ideastatica.com/support-center/user-defined-material-material-and-product-range-library-mprl
Hello, if you mean to combine vertical and horizontal anchors in one block? This is possible as a workaround - you model 2 overlaping blocks and assign each anchor group separately, just you dont get the interaction between them.
Hello, unfortunately, the code checks for anchors under the SP code (Russian code for steel) have not been implemented yet. According to demand from our customers and the evolution of the conflict and restrictions from the EU towards the Russian Federation, we can later continue on that. Regarding the SP code implemented in IDEA StatiCa www.ideastatica.com/support-center/check-of-components-according-to-sp
Load effect Axial load 145 KN is it comprssive or tensile force. If it is compressive.it should be with negative sign. If it tensile,it should be with positive sign. Could you clarify this?
If the friction option is used to transfer shear force, only the friction resistance between anchoring plate and concrete is checked. Therefore no shear forces are imposed into the anchors. With the option 'anchors for transferring shear force' it is the vice versa check.
Hello Loc, we have some new features of the model in the newer version, therefore the results can be slightly different. If you want to discuss your results, you can contact the local reseller for your region: www.ideastatica.com/resellers/

Hello Aleksej, as far as I understand Russian, you are asking about the reinforced concrete of footing: it is not possible at the moment, because it needs 3D modeling of the concrete block. This is in the plan for future development.
Looks nice - but how shear is tranferred from all anchors GRD1,GRD2,GRD3 and GRD4 (each is independent of other).Shear lug could be set-up only for one of them eg. GRD1... all others GRD2,GRD3,GRD4 could be set-up to transfer shear only by friction or by bolts but not by shear lug!?See 35min of this video - there is showed only shear lug set-up for GRD1. How shear is set-up fo GRD2,GRD3 and GRD4?
Hello Jolanta, yes, you are correct: shear lug was set in operation GRD1, but it is valid for all of the anchors, which are connected with this base plate. It's just a way of entering in IDEA StatiCA Connection. For one base plate and its anchors you can choose only one option for shear transfer (friction; shear lug; anchors) and it is valid for each anchor connected with this base plate. If you want to learn more about shear force transfer, please check or Theoretical background (Chapter 4.7): goo.gl/yZvRDf
Thanks for quick reply...I've just realised that copy of GRD1 (GRD2,GRD3,GRD4) create new foundation block for each of them and should be changed for every next GRD operation to "existing block" :).It will be nice to see all operations in detail - I had a lot of try and errors with stiffening members especially which type to use and in relations to which member...
Hello Jolanta, we are glad, now it is clear about anchoring. For other questions (about different topics), please contact our helpdesk team (helpdesk@ideastatica.com)
Regarding the rod anchor, I did the same exercise and the concrete block fails 262.1> 100% I think it miscalculates the compression area. use version 10
Hello, thank you for your comment. The commented video is done on version 9 or 9.1. But there might be more reasons for the difference.

About heavy anchors with washer plates, the concrete cone check acc. to ETAG 001 is inappropriate. ETAG 001 is for anchors for which the holes were drilled on site and anchored by mechanical or adhesive means. So the washer plates are totally different case. It is close to impossible to design correct anchors with washer plates for high tension forces in IDEA StatiCa... I hope this will be fixed in near future.
That is not true. As you can read in ACI 318 (code for concrete design used in USA), CSA A23.3 (code for concrete design used in Canada), SA TS 100 (code for anchorage design used in Australia) or draft of EN 1992-4 (code for anchorage design that should be published at the end of this year), the scope of the design is also for cast-in anchors and in some cases, washer plates are mentioned. The used formulas are nearly identical in all codes and in ETAG 001 Annex C. All codes are based on Concrete Capacity Design developed at University of Stuttgart mainly by prof. Eligehausen. The engineering practice of steel structural engineers is mostly that we check only steel failure of anchors, design quite long anchors and leave the concrete and concrete reinforcement design to concrete engineers. Even high forces which are not possible to transfer by plain concrete (ETAG 001) can be transferred via concrete reinforcement (as suggested by all other mentioned codes). IDEA StatiCa Connection is not a software for design of concrete reinforcement but we started to show a force which need to be transferred via supplementary reinforcement so far in AISC and CISC since version 9. We will continue to upgrade the software and anchorage design and switch from ETAG to EN 1992-4 soon after it is released.
What I mean is that ETAG 001 Annex C says the following: Point 2.1.1 "This Guideline applies to metal anchors placed into drilled holes in concrete and anchored by expansion, undercutting or bonding, as described below and shown in Figure 2.2." In my engineering practice, I've came upon many anchors with high uplifting force. The anchoring plate and lengths of anchors was one of the critical points in design. And unfortunately, as a steel structural engineer I had to specify the dimension and thickness of anchoring plate and anchor length. I just think that with what you have already in IDEA StatiCa, it should be possible to provide a check for anchoring plates also. With the default IDEA StatiCa settings, each heavy anchor will be "incorrect" due to concrete cone failure, the correct approach in such case is to turn off concrete cone failure check and design the anchor plates (and anchor lengths) manually, which should be mentioned in this video, especially since it's focused on anchoring.
Yes, you are right. Heavy anchorage can hardly be designed without supplementary reinforcement. That means turning off the concrete cone breakout check. The pullout failure check for anchors with washer plates for EN will be included in the next version of the software according to fib 58 (which is the same as in draft of EN 1992-4).
I saw in the video time 23.04 the anchor bolt 4 does not take any forces and its Utt around 0. Is there anyway to distribute the shear force to all anchors? Pls clarify this.

Load effect
Axial load 145 KN is it comprssive or tensile force.
If it is compressive.it should be with negative sign.
If it tensile,it should be with positive sign.
Could you clarify this?
It is tension - the arrow points up, the sign is +.
If its compressive, the value has - sign.
What is the difference between friction and anchors for transferring shear force?
If the friction option is used to transfer shear force, only the friction resistance between anchoring plate and concrete is checked. Therefore no shear forces are imposed into the anchors. With the option 'anchors for transferring shear force' it is the vice versa check.
