Concrete Block Masonry Reinforcment

[Muhammad Adnan Alam]

i am doing my final year project and the project is related to concrete block masonry reinforcement to make the masonry buildings seismically strong. i want to know that is there any software which can be used to design and analyse the masonry structures.

[Shahbaz Bangish]

what masonry code are u using?

with reference to your post here.

Thanks for explaining the situation. I assume you are using ACI provisions for masonry. There is a software called Structural Masonry Design Systems. You can use the trail version of it. You can download the trail version by clicking here.

The trail version has only 3 restrictions, but you can do complete analysis as none of it hinders you to perform a full design.

The following limitations have been imposed on the free trial software compared to the for purchase version

• 
  
  1. Reinforcing steel is limited to Grade 40 only
     
  2. The saving file has been locked out so that a design cannot be saved.
     
  3. The printout displays the following message: “FREE TRIAL VERSION – NOT FOR DESIGN"
     

Review the link posted below to see the examples(the seminar handouts).

I hope that helps

sir i am already using this software and have designed wall but as far as analysis is concerned this software does not give it and it does not give the response of structure in relation to seismic loading. we are in need of energy and stress contours of a wall so that we could check where the reinforcement is to be provide . basically we want to give analysis first and then design.

thanks for response need such help in future and also i have checked the MASS software but could not get it because of online payment. is it possible i gave you sketch of our house and you design it on MASS and then send us the results because it will take a lot of time to understand and learn the software first .

Oh i see! for analysis you can use Etabs. When you first mention using etabs for masonry you said design. Anyways for analysis you can use it or any other frame design software that supports shear walls. Just define the walls and diaphragm. Run analysis, get stress and forces and then use them in your software. Can you post the drawing of structure you are trying to analyse? I believe your system is a confined masonry system with masonry shearwalls. Please confirm.

Thanks.

MASS is a design software only. Its easy to do analysis on any frame software. All we need to is to set it up correctly. It would be great if you can post the sketch/drawing of the house! Then we can decide how to analyse it in etabs!

thanks for positve response. i will send you the drawings , tomorrow mornings.

Use TNO DIANA.I am using it for prediction of damage in old masonry buildings due to tunneling operations. This software is the best I hv used so far with modelling capabilities for seismic,geotechnical,hydraulic and tunneling problems.

sir i am sending you auto cad files of our drawings. it is basically a two room office building. and we have to analyse it for seismic risk for zone three. in next phase we will provide reinforcement and then using section designer option we will check the stress again on the same wall

i tried to send the real files but wan't allowed to upload such files so i am sending you images of the drawings

got my files or not?

I m away from home! I can reply you in detail only when i get back!

sir basically our project is divided into two parts one is for non-frame masonry and the other is infill walls in frame structures because both are highly vulnerable to earthquake damages. the images of frame structure , i will send you tomorrow and i will myself try to analyse the wall on ETABS. we have already designed the frame portion of our project and now we are working on infill walls and non-frame structure.

[UmarMakhzumi]

Sure just attach you sketches here so others know too that what is going on and can comment.

[Muhammad Adnan Alam]

one more thing i would like to ask that what joint properties we will assign to walls in non-frame and in frame infill wall. i mean to say wether that would be hing or fixed support

[Muhammad Adnan Alam]

ok its three o,clock now ALLAH HAFIZ see you tomorrow.

[UmarMakhzumi]

I have added .dwg file extension to database, so now you will be able to upload cad files. Just attach your files here. You many also want to consider using another software once the 1st pass is done by Etabs to verify your results. I will recommend TNO DIANA as Sir Badar mentioned above or 3Muri mentioned by Yasir(Nustian371) here. You can use hinge(pin) at base as it will result into a more conservative design.

i am working on the given sketch and want to analyse the stresses of masonry walls. any body who can help me????

I dont have cad so cant see what your layout is, but what I can do is that I have created a etabs sample that will help you understand how to get stresses from walls. When you want to report stresses from walls you have to assign them pier labels, like I did in the attached file. There is a horizontal load of 20kip in Y-Direction. For your own case, define walls, assign them proper strength and material properties of masonry, assign pier labels, diaphragm and apply lateral loading and report your stresses or forces for pier labels assigned. Hope it helps!

yar i would recommend that u use SAP2000 u can get a cracked verion on cd in the market it can seisimc analysis but wat sort of analysis are u dealing with time history analysis or pushover analysis. But u cant define joint properties between maonry and the concrete confinements it will go with the default parameters. plus masonry is a non-linear material so u should know how to input those material properties. Plus there is another software ABAQUS but its not used in pakistan and it is quite difficult and less user friendly as compared to SAP2000 because it has varied application in different engineering disciplines. I did a similar project in my MSc and i did it in sap2000 but it was not quite in depth just a comparison between unconfined and confined masonry.

Considering athers reply, my post holds true if you are doing anaylsis by Equivalent lateral force method.

Whats going on..? any update or breakthrough ?
