Dear Sir,
I will really appreciate if you can tell me what is the limit for KL/R ratio for X brace, single diagonal brace,K brace, V and inverted brace V for high seismic area ( AISC341-05) for compression member. UBC 97 use to have limit of 720/sqrt(Fy). In AISC-341-05 for ordinary...
Hi friends ,
I am new structural engineer in the firm. I was told to read the latest code ACI-318-05 for anchorage(Appendix D). I will appriciate if some body can tell me difference in the design for cast in place anchors and post installed anchors.
1.0 Concrete break strength of anchor...
Hi Friends,
I am designing Anchor Bolt for tank using strength design method (ASCE7-05). As I understand we need to use to Eq. 5 and 7 to get tension on AB, i.e.
(1.2+0.2Sds)*D+ Over strength Factor*QE Eq 5
(0.9-0.2Sds)*D+ Over strength factor*QE Eq 7
In Eq 5 :
1.2 and 0.2Sds...
Stephen,
Thanks for replying back. Let me rephrase may questin, may be I was not very clear in my first post. It is not the tank I am designing. It is the support system , as these tanks are elevated 1.5' above the ground by steel coulmn.
I need to have base shear of the tank to design...
Hi,
I will really appriciate if somebody can tell me how to calcullate base shear of non building structure when fundamental time period is more than 0.06sec.
I can find V = 0.30SdsWI (Eq 15.4.5-ASCE7-05 ) fundamental time period less than 0.06 sec.
can we just use V=0.03XW ( section...
I am working on a project which is in malayasia. They want us to design modules as per UBC 97 for both seismic and wind. I was reading ubc 97 for wind and found there are two method for wind design ie normal force method and projected area method. I will appreciate if somebody can guide me the...
Thanks for replying for my query. I am new structural engineer and I found plates were provided in the drawing ,which I was reviewing.My project manager told me it is wrong. I am trying to understand why some structural engineers are using it.
Should achor plate be used as anchorage at bottom end of anchor bolt.
TVA made research on this subject in the early 80s. I would like to recieve information on this subject
