Colleagues, I have been using ANSYS to model concrete strengthened FRP sheets, but less than happy with it. Any has recommendation for efficient, easy to use FE program for modelling concrete strengthened with FRP sheets?
Osama Ahmed Mohamed I suggest you give SAP2000 "layered shell element" a try. this element will give you 5 active layers, linear or non-linear at your choice, one for concrete in the middle, 2 on each side for two layers of reinforcement which you can manipulate to use FRP, rebar or a combination. I have done variety of retrofit project with it, and I have been quite happy with the efficiency and economy of the results. Good luck to you
Osama Ahmed Mohamed, can you please give some more information on the model - what do you use it for, are you modeling separate elements or entire structure, etc. The choice of program is strongly dependant on the goal. For everyday design purposes ANSYS is realy heavy, I agree, but it may be just what you need for more complex reaserch models, for example if you need to explicitly model the concrete-FRP conection. It takes time to get things working sometimes.
Else, if your priority is time and efford, you can also model your structure as reinforced concrete one with your prefered finite element or building information program with some adjucement of the input data (again, depending on what are you aiming at)
