While analyzing a structure for response spectrum seismic loading the response(base reactions, member end forces, etc.), comes to be in absolute value. This is due to the fact that the responses coming out of several modes are combined by using some predefined…

I'm getting some conflicting graphical information and output. I'm designing a special concentrically braced frame (SCBF) with wide flange beams and columns and HSS braces. The frame column webs are oriented in the plane of the frame and all beam and…

Dear sir, When we design steel structures using Indian standard IS 800, If Design parameters of SEISMIC as per Section 12 of IS 800 will be checked as follows: At the same time, Response spectrum analysis had already been performed in model. But…

Currently Working on Pipe rack Design for the New Zealand site. And I want to do Seismic analysis for the pipe rack. I have seen the seismic code list which is available in software. New Zealand Seismic code is not available in code list then how we can…

Does anyone know how Ram Elements calculates Computed Spectral Values when doing a seismic Response Spectrum analysis? Given an input seismic response spectrum (a table of structural period and related seismic accelerations) In Ram Elements outputs…

Hi - I was hoping that someone would have some further information on how RAM Frame calculates the seismic stability coefficient (theta). When I do a quick hand check of the numbers given in the report, I find that the reported thetas are significantly…

I am running the seismic analysis for a 3 story structure and have questions about how to determine the appropriate building period to use for the seismic analysis. Gravity system is typical steel frame, with composite slab/framing at 2nd and 3rd Floors…

Dear sir, Greetings. the definition of problem as " A vertical continious beamcolumn frame with RCC Infill Wall (to support earth pressure) supported laterally with main structure frame at slab level " I am modelling a multi story RC framed structure…

Hi all the staad reference load is necessary for checking the soft stories. But I have a doubt while defining reference loads the live load has to reduce as per the specified code or we have to assign full live load in the reference loads? Because the…

Hello. Why do we have to generate seismic loads first and then the other loads after seismic loads? How can I find the seismic weight of the structure so that I can generate the seismic loads similar to floor loads instead of copying my DL and LL under…

Hello Experts, While analyzing the model by response spectrum analysis, I do receive the following warning while specifying seismic direction as "Y". ***WARNING : EARTHQUAKE MODE IS NOT AVAILABLE FOR X AND Z DIRECTIONS **** Whether this can be neglected…

Hello Experts, I am not well versed with the dynamic analysis, since we could not perform linear static analysis for seismic load application as per Eurocode, Someone please guide me how to apply the response spectrum properly as per Eurocode. I tried…

Kindly do clarify my following doubt 1. I have attached three model a.static analysis model b. Dynamic analysis using reference load method c. Dynamic analysis without the use of reference load method a. Static method STAAD SPACE START JOB INFORMATION…

Good Day Everyone I do have a quick question regarding Seismic Load. Q1. If I have the total mass for seismic design as Force (kN), then I apply it to center of mass/gravity of my structure, How can I transfer it to the nodes in the structure? Is…

Good evening, I need to perform static seismic analysis according to Eurocode Standard (evaluation of equivalent lateral forces of a structure at each level/floor). Is it possible with STAAD_Pro ? Is there a procedure to follow or some examples availabe…

Hi, I am designing a large single storey building along with foundations in Seismic conditions. The load cases i am applying are: 1. EQ X Direction, 2. EQ -X Direction, 3. Eq Z Direction, 4. EQ -Z Direction, 5. Dead Load, 6. Live Load …

Good morning, I'm trying to perform response spectrum modal analysis with Response spectrum user define data option on a multistory concrete building. The porpoise is to introduce in the FE model, seismic actions according to Italian design code (NTC2018…

SIR I WANT TO KONW WHY MASS IS PROVIDED IS PROVIDED IN GX AND GZ DIRECTION IN MASS REFERENCE LOAD CASE.

i have a doubt in seismic design that i have done in seismic design is correct or not can u plz check and suggest what should i do next. AISHWARIYA.STD

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 guys, I' m trying to make a seismic analysis, using the response spectrum (EC8) from the "load item" list. In the second phase I' m define one spectrum in x and y direction (direction parameters 1 and 0,3), specifying the masses (selfweight, live…

I am designing 3-story Eccentric Brace Frames using the Seismic Provisions in RAM Frame and I am confused with the required strength value that is being determined for the axial design of the 1st story column. The Member Code Check report for the column…
