    Help to find Seychelles Wind and Seismic Code.

    Hello Everyone, I'm an engineer working on a project on Seychelles Island. I'm trying to find information about the building codes that applied to an existing project constructed in early 2010. Actions on structures are mostly what I need. I've been searching online, but I can't find any...

    composite steel deck + regular slab connection

    Hello, It is required to put the bathroom POD before casting the upper slab, so no shoring is possible, as there is bathroom POD. MSc. Eng. Serguei Joa Structural Engineer Bouygues Batiment International, Cuba.

    composite steel deck + regular slab connection

    Thank you @HTURKAK That is exactly the idea, But a regular formwork is not working over the bathroom pod, to be installed, so I am looking to put some permanent formwork (sacrificial). MSc. Eng. Serguei Joa Structural Engineer Bouygues Batiment International, Cuba.

    composite steel deck + regular slab connection

    Yes, I agree that the shape of the deck reduces the overall thickness. But we plan to drop it's level to allow the needed thickness of slab over the deck. MSc. Eng. Serguei Joa Structural Engineer Bouygues Batiment International...

    composite steel deck + regular slab connection

    @phamENG. Spot On! The aim is just to ease the execution part of the solution, as we have no clear height between the Pod's Top and the Bottom of the slab to be cast, I am not expect it to work as composite in any part. Slab is 225mm thick and the recess is 50mm. I have designed the slab with...

    composite steel deck + regular slab connection

    Thank you @HTURKAK please have a look at the scheme. I think it is good enough, though a bit of waste as the deck is not considered collaborating, just permanent formwork on top of the Bathroom POD. Thanks for the time, to look at my issue. MSc. Eng. Serguei Joa Structural Engineer Bouygues...

    composite steel deck + regular slab connection

    Hello phamENG, Thanks for replying, Yes, the slab is continuous on the other end, the scheme is a continental frame for residential apartments, so the span is about 7.5m by 7m, too much for the deck, the idea is to support the patch of "formwork only" deck, i would keep same reinforcement and...

    composite steel deck + regular slab connection

    Hi to All! I have found a difficulty finding an example of joint between a regular plain slab and a composite slab. The problem is that I need to create this joint in an unusual place (middle of the span), we are trying to figure out the solution to cast in-situ slab over prefabricated...

    Warning in Non-linearly Static Analysis in Etabs 2016

    Hello, I would follow exactly the Analysis Log advice: CHECK THE STRUCTURE CAREFULLY FOR: - INADEQUATE SUPPORT CONDITIONS, OR - ONE OR MORE INTERNAL MECHANISMS, OR - ZERO OR NEGATIVE STIFFNESS PROPERTIES, OR - EXTREMELY LARGE STIFFNESS PROPERTIES, OR - BUCKLING DUE TO P-DELTA OR GEOMETRIC...

    ETABS placing wind load on line elements or on each diaphragm pros and cons.

    @JasonMcKee71 Thank you for your response, additional to you statement: In case of designing the cladding or glass curtain-wall, I would place the wind load of the edge of the slab to get the wind forces locally. Best regards! MSc. Eng. Serguei Joa Structural Engineer Bouygues Batiment...

    ETABS placing wind load on line elements or on each diaphragm pros and cons.

    Hello everyone, I am working with a structural engineer form other company and I am having a hard time to convince him to place the wind loads as concentrated in the diaphragm. I have the impression that there are losses of load when the horizontal load is defined on lines. Could you give...

    Etabs - Importing or editing default load combos

    Hello, Two suggestions: 1. Make sure all of the loads mentioned in the combinations, exist in the define load section. 2. Writing in the notepad, make sure you give two spaces at the begining of the line. Regards. MSc. Eng. Serguei Joa Structural Engineer Bouygues Batiment International, Cuba.

    Modal analysis of a tower.

    Dear all, Thank you for your answers! After cracking my head, I asked the same question to the engineer, who modeled the structure. he just told me that he had to open the building's core and that made the periods go crazy. Now I have received the correct model and it is preforming ok. Best...
