    ASCE 7-16 Vehicle impact load

    Thanks JAE. Perhaps we missed that section. i'll look into it. F=ma requires some assumptions ofcause. One can make them, and aim for the values that by experience should be designed for. For information Eurocode also consideres an energy approach with F=0.5mv^2/d, where d is the deformation...

    ASCE 7-16 Vehicle impact load

    Hello, A parking garage designed to ASCE 7 and concrete to ACI 318, needs consideration for vehicles impacting the columns and other structures within the parking facility. Is there prescribed load values, or is one expected to take an approach of applying F=ma, assuming maximum mass and...

    ETABS Modelling a long column

    I would typically overwrite column length in design parameters, for these selected columns, and let meshes be at levels.

    displacements one story vs 2 stories

    Above is correct. Elements will be split at levels, and masses will be lumped in more points along the elements.

    I have it. I just can't find what I am looking for. I need a clause describing the combination of directional wind loads to 'diagonal' loads.

    EN 1991-1-4

    Hi all, I'm having trouble finding instructions on how to combine multidirectional wind loads according to EC. I have my windx and windy (wind in main directions x and y of my building). But in my sense of logic these should be combined with 1.0*windx+0.6*windy or similar. However i can't find...

    etabs and revit structure

    Using CSIxRevit you can import your model in .exr extension into Revit Structure. My experience is however that some elements, especially meshed area objects, may be exported/imported wrongfully. After import you can use the model in Revit for whatever functions you wish.

    OpenGL viewer

    Hello, When i make an animation in the OpenGL viewer in ETABS, the .avi file does not contain any frames. Everything looks ok in ETABS when making the animation, but the result is a blank video file. I have updated gfx drivers and run ETABS 9.7.0 on win 7 64bit. Hope someone can help me asap...

    Design wind speeds for countries outside USA.

    Hello, I usually use Holmes' Wind Loading of Structures Appendix D. Here an overview of wind conditions in diffrent countries is listed. Hope this helps.

    Mass distribution

    Thanks for your reply slickdeals Could you be more specific with regards to which table? As far as i can see only the building modes diagram lists date for each storey, but the only data here are the displacements of each mode.

    Mass distribution

    Hello, I need to know the mass of each story of my building. By this i wish to output a list of mass along the building's height at points corresponding to those where my stories are defined. Hope someone can help me. -Konnerup

    PIER names can not be replicated on v9.7.2

    Hi, Then i can only inform you that v9.7.3 does not copy pier labels either. Good luck with resolving the issue.. or reassigning pier labels at all storeys.. -Peter

    PIER names can not be replicated on v9.7.2

    Hello, Pier and spandrel naming must be unique for the elements associated with one level of your building. So you can't have two P1 piers on the same level, but you can have a P1 pier and an other P1 pier on different levels. Does that answer your question? -Peter

    Windows Language

    Hello, My objective is to make a simple FEA program with a GUI for a Windows (Vista/7 32/64bit) platform. My skills in programming goes as far Matlab scripts, so you can easily say I’m a newbie to programming. My question is: Which language will with 'simple' programming (as similar to...
