• How to model transportation acceleration in Staad.Pro?

    Dear All, I would like to ask if, and if yes, how, is it possible to model acceleration due to land transportation in Staad.Pro model? I would like to be able to apply an acceleration value at the COG of the structure and have it applied to all the…
  • Calculation of the response factor

    A question about the calculation of the response factor within RAM Concept: When reading the RAM Concept Manual to understand how the response factor is calculated within RAM, the manual states that the baseline acceleration, alpha,RMS = 1 m/s2 (see…
  • STAAD.Offshore Weight Factor

    Hello, I'm trying to get an understanding of a weight discrepancy between my results in STAAD.Pro and my results in STAAD.Offshore. When I run a simple gravity case for a structure in STAAD.Pro, I get a resultant weight as a sum of the y-reactions…
  • RE: Mine Fan Foundation - Dynamic Analysis

    Yes once you carry out the time history analysis you can go to the Postprocessing > Dynamics page and get time history of the velocities, displacements and accelerations as shown in the screenshot below. If you need the time-history data based on which…
  • RE: Seismic Analysis of Boiler Support Structure - Find local structural accelerations

    You are welcome. X1 X2 X3 represent the translational accelerations in global X, Y and Z directions and are reported in terms of g values. X4 X5 X6 represent rotational accelerations about global X, Y and Z and are reported in rad/sec2.
  • Floor vibration

    Hi, I'm studying the floor vibrations on a model that consisting of three floor A, B and C, despite floor A and C are symmetric, they show different ultimate acceleration because STAAD considers one of the girders only for calculating the results of…
  • About UBC Seismic Load

    Is there anyone tell me why the following error appeared? the attached is the staad pro file. for MVXR MK4.std
  • dynamic loading

    i am designing monopole antannae, the vibration conditions are 1-) 23Hz to 50Hz with pk to pk 1.6g, 2-) 50 to 150Hz at 2g.How do i use this data in staadpro and how do i provide the damping? Thanks all
  • Gravity tilt & Load factor in Staad offshore

    Dear friends In Staad offshore we have option to include gravity load effect by clicking Gravity tilt. My question is can we able to consider Gravity tilt for few load case included and few load cases excluding gravity tilt. when i tried its either…
  • Vibration of Machine

    Hi friends, I have to model the structure for foundation of machine. The structure is only beam column and I need to input the vibration of machine on top. I assumed the vibration is 30% of machine' weight (4 ton). And I devided by 4 because each machine…
  • How to apply horizontal load at the center of gravity of equipment?

    Hi, I want to apply horizontal load at the center of gravity of equipment (due to wind and acceleration), however only the base or foot print of the equipment is modeled in staadpro. Are there any options to do this in Staadpro other than applying…
  • Response spectrum analysis - acc file information.

    The option of saving the accelerations file used in the response spectrum command will generate a file with the extension ".acc" listing the accelerations of all the joints in the structure. Question: Is the information provided in the ".acc" file accessible…
