More than anything i am worried about the precedent this case is going to put on rest of community if you allow such light fixtures be installed on trees in such heavily wooded area. What is there to stop others from adding more of it on rest of the trees as time progresses. How would you...

Thanks Mike for your inputs. I am already very clear about flexible vs rigid diaphragm and governing codal clauses. However, my only concern were the joint lines long the double tee spans. Inherently, the entire rigidity of the diaphragm would depend upon the embed connections that are joining...

Thanks a lot everyone on your inputs. I think for now I would go with the assumption of considering it rigid. I did find few other references and research articles to support this and I think i should be fine with it for now. No specific codal requirements like chapter 21 of aci318 cover this...

Hello everyone! I am currently designing a 35 foot high warehouse with LFRS system consisting of precast wall panels and with roofing made up of precast/prestress double T joists which would be interconnected along joint lines as per MFR design guidelines. I have assumed that the diaphragm is...

I just heard decision has already been made and most likely its going to be RAM Connections. Again thanks all for your inputs.

Hi everyone, Our company was planning to buy Ram Connection software package from Bentley. I was just wondering is there a better alternate to this? Cost wise aswell as one with better user interface. Thanks in advance! --Ad

Hi all, I was wondering if it is possible to model a sloped flexible diaphragm in etabs. I could not find a solution for this modeling problem. Any suggestions would be highly appreciated. The reason being I am modeling an overly complicated single story building (thanks to the ARCHT) with...

Hi all, I was designing a rectangular base plate (i.e. longer in the direction on brace frame) for a SCBF HSS column with net tension and shear. And was was wondering whether the base plate needs to be checked based on the interaction ratios for both these force components. In my case I have...

I have mezz level addition to existing bldg completely independent of the exist frame. This new level framing will have composite deck resting on steel beams. Due to existing frame I have to design some of the beams as cantilever beams and so was wondering if I should just design them as steel...

Hi all, I was wondering if anyone could provide me with a good reference example on design of composite steel beam continuous over support. Thanks in advance.

Hi all, I am designing 8 story industrial steel structure with SCBF system. Its a pretty symmetrical square box kind of structure and with loads at different level. I ran it in Etabs and wanted to cross check results manually for column design. I wanted to know if the columns whihc are also...

Hi everyone, I have 4 story (+penthouse) wooden bldg (rectangular in shape 310'x110') which is partially bearing on concrete floor at second level and partially bearing on concrete floor at first level (i.e.) there is a rigid and flexible diaphragm at second floor level. The joint between two...
