Dear all, Error found during the seismic definition analysis. Found the error "no unsupported masses found - check densities" . Kindly help me out from this . COLLEGE PROKECT.STD

Hi, I have a doubt in STAADP.ro CE about how can I implement the factor Bheta 1 and Bheta 2 in Steel Design (Appendix 8 AISC 360-16). I know that it possible to perform P-Delta Analysis, but for seismic design with modal analysis/response spectra, I…

Hello, Currently, I am using STAAD pro Connect edition's latest version. Following are question mainly targeting of RCC and Steel structure design in STAAD Pro and in other Bentley tools per Eurocode with German N ational Annex (NA). 1. Can…

How does RAM calculate the period for a building that has separated diaphragms. Attached is an image of two towers that are connected on the bottom three floors and then are separate the rest of the way up.

hello i am student working on project Rc frame subjected to seismic forces (ibc) and wind also but i couldn't because most of tutorials are on steel frames and i need to work in rc frames can any one provide some examples also i dont understand…

The session “ Increase Your Digital Productivity with STAAD.Pro CONNECT Edition ” was conducted on 6th Dec 2018 at the Digital Advancement Academy, Pune, India to demonstrate the improvements to modeling, analysis and post-processing, along with design…

Hi all, 1) Is there a way to set the ground level in STAAD Pro or is the y=0 level the permanent ground level? This is for the purpose of computing the seismic forces because, from what I know, distribution of the computed base shear per level of a structure…

Dear Members, can u please guide me how to do seismic analysis in staad for the portal type structure(Integral). span is for 24.0 portal-model .std m and here am attaching a model for 10.0m

hi, I have some questions about the connections design procedure and detailing by RCSA. I) Does the "RAM connection" really use of "AISC 358-16" code provisions? for example, recently I have checked a bolted flange plate connection and noticed that…

Hi Good Day! I would like to raise my concern in my STAAD model regarding the distribution of seismic forces. Currently, I can't find a way to achieve my desired mode shape which is translational for Mode 1 and 2, and torsional for Mode 3. Though I…

When doing the foudation overtuning check, how does the program deal with the seismic load from foundation itself? I couldn't find any option to specify seimsic parameters. I am assuming we need to apply the seismic load from the foundation itself from…

When using RAM Frame for a seismic analysis, is it possible to set the response modification factor to a certain value such as 3 in the event that you are using Seismic Force-Resisting System H in ASCE 7-10 Table 12.2-1 which is for "STEEL SYSTEMS NOT…

From the STAAD technical reference, section 5.31.2.1 UBC 1997 Load Definition "C t < 0.42 if the units are in feet, and C t > 0.42 if the units are in meter." From UBC 1997 WHERE: C t = 0.035 (0.0853) for steel moment-resisting frames. C t = 0.030…

Hi, 1. Does STAAD take into account the ductile detailing provisions of CHAPTER 21 of ACI 318M-11, while arriving at the reinforcement area and stirrup area ?? 3. If those provisions are available, how does STAAD identify a SMRF or IMRF or OMRF in…

Is it possible to do Seismic Definition in STAADpro for SNIP (Russian) standard

Can someone please give me the STAAD input text for seismic to UBC and to BS EN 1998 - I find the STAAD help editor difficult to follow. I am assuming that I will use CQC for the modal analysis, but what about SRSS etc. In the example I have pulled…

Hi, I am unable to generate seismic parameters in STAAD. I am using STAAD SS 6: 20.07.11.33
