Staad seismic

lachin nuriyev — Tue, 22 Nov 2022 10:42:48 GMT

Hi, I have to design a storage tank for seismic. In seismic, I added loads to the seismic load case in x y z directions to make seismic mass. In API650 there are load combs. In load comb f there are dead load(Selfweight Dl) and stored liquid load (Pl), I have added these two loads in the seismic load case to gain seismic mass. my question is should I add Dl and Pl loads in combination F or I should extract these loads from the combination, why do I say extract these loads I think in the seismic load case I already added these loads in x y z directions. Please help me to make sure about this

Staad.Pro I section+plate

lachin nuriyev — Thu, 10 Nov 2022 05:50:34 GMT

Hi. I need your help to clarify my decision. In our design, we have an I (W) section and an above plate, I want to add plate thickness and some length to the I section up flange. When I analyze the model, I section has a UC ratio of 1.5 but when I add plate thickness to up flange, the ratio goes down to 0.1. Is that the right approach to add plate thickness to the I-beam up flange?

Hi. I use the response spectrum seismic method. I should apply permanent loads on 3 directions (x,y,z). I attached an image that indicates some loads in 3 directions. Is that correct?

Staad.Pro - Seismic loads by response spectra

Hi, I need help defining seismic loads by using the response spectra line graph. I add seismic periods and accelerations in the 'Load Case Details' section (attached image). I did not use the 'Definitions' section to consider seismic. My question is how to add loads to gather seismic loads in load case 12. I have used repeat load. Is this approach correct?

Staad Foundation

Hi. I am having trouble with Staad Foundation. I created a Tank foundation to analyze. The storage tank roof has a lot of elements such as the W section under the tank roof plate. In Staad foundation we can only consider roof plates, bottom plates, and tank average thickness. But doing that does not get me the actual weight of the storage tank. To consider actual weight I add some loads in Miscellaneous Dead Load (Misc) section (attached picture), but afterward, the results do not change. I have done it for different numbers of load values but it was meaningless, the result did not change. Is there any possible way to consider the weight difference in the Staad foundation to get the actual weight?

Offset method

Hi, I want to find out is it appropirate to split Dia 820 beam to connect beam Dia 630 in points 1 and 2 or i must connect them in centerpoint then use offset command. Same for points 3 and 4, there is small gap between these points
