HELLO EVERYONE,
I WANT TO calculate the required torque for the pre-tension joints, i don't have much experience in this so i hope to find a help in this regard
Dear Gents,
i have simple structures .and I want to design the moment connections between beams and columns based on aisc design manual 13 th ,because i don't have the end forces for the members ,
so i will use a percentage from the capacity ,
1-what is the accepted percentage and its...
Dear Experts,
i have one question about design of base plates which affected by uplift force and large moment ,
i want to know how to determine the bearing length at bearing interface ,i didn't find any reference for these type of plates.
and i don't think that equation (3.4.3 in AISC design...
Dear experts,
i want to know how to check drift results using dynamic analysis ( response spectrum analysis ) , the traditional method that going to show tables in etabs and select show drift then see the drift in RSA in x or y direction will not work because (as i think ) etabs calculates...
hi guys,
i seems logic that using stiffeners in base plate will decreasing the base plate thickness ,however i can't find any reference or guide to calculate the stiffener effects,
aisc design guide for base plate shows the rigid cantilever method for base plate design without stiffeners ...
Dear experts,
I am using sap2000 v18 in design steel according to aisc 360-10 and as code required for all load combinations we must perform second order analysis including p delta effect , and the problem coming here sap is taking very long time during analysis, I want to know if there is...
dear experts ,
i want to link text box with cell in order to make the cell read the numerical values from the text box to use this value in the sheet equations,
thanks in advance
Dear experts,
hi every one ,i don't have much experience in production of steel members ,so i have some questions for experts here,
first,
what is the max thickness that can be accepted to make cold formed steel members like (C -channels .Z channels)
2-for hollow square sections with small...
Dear experts ,
I am confused when I use chs, shs & RHS SECTIONS with small thickness (less than 4mm) such as chs 48.3x2.6 and similar ones
my question is ,should I use AISE DESIGN CODE and consider it as cold formed profiles or use aisc
THANKS IN ADVANCE
hi every one,
I have to check sap model for truss members with span 42 meters, I have two questions:
1- I want to ask about design parameters, in the model that I have all design parameters are program calculated "the designer didn't make design over right for any thing" is this right?!!
2-...
Dear experts,
wish good day for all
I want to know if there are any recommendations for the maxi. distance between the bracing bays in metal buildings "ordinary hangers with cranes" , I can't find any thing in AISC about this issue.
I used to make the maxi. distance between bracing bays not...
Dear Experts,
I am looking for powerful software to design petroleum storage tanks using API 650, actually I have little experience in this type of steel structures
I have to choose a good software to handle this task ,and i got offer from " AMETANK software " as the best software in this...
dear experts,
I want to ask about notional loads
first in direct analysis method according to AISC360-05 or AISC360-10 I have to used notional loads which equal 0.002 from gravity loads and apply it for each story level ,but there is condition in code where the ratio of maximum second-order...
Dear experts,
I write this thread in AISC steel construction group but I didn't find any response
I hope to find answer here , I am sure that experts here deal with this issue before
"I want to check fatigue for crane gantry girder according to AISC , I really need help , I don't now how to...
Dear experts,
I want to check fatigue for crane gantry girder according to AISC , I really need help,I don't now how to start
I will be pleased for any help
thanks in advance
Dear experts,
I want to calculate the seismic effect for an elevated steel water tank
it's about 10 meters height
how can I take the effect of seismic in water inside the tank during earth quake
thanks in advance
dear experts,
1-can any one explain to me what is " f12 " in shear wall modifiers represent for ,
as I know f11 & f22 represents for shear plans in y and x axis,
but I want to under stand "f12"
2-also "m12" in slabs what is represent for
thanks in advance
greetings for every body,
I have one question, which is better when I want to design multistory steel building (five floors). using STAAD or ETABS according to American code??
I think STAAD is better in steel design but it has some limitation for example.it can't take the eccentricity for wind...
