    Unbraced Length Ratio (Major and Minor)

    Dear colleagues, Let's imagine that we're working on a metallic beam with 10 meters length and it was devided in 6 frames for a better analysis. The working code is the Euro Code. After running the Design/Check of structure, I verified that SAP2000 assume values, which I think they are for...

    Triangular steel column

    BA [thumbsup2]. And please don´t spend time around my last consideration. I believe I reach what I want crossing information from two different models. Hej då alla ni agps

    Triangular steel column

    I forgot to explain that the value 56 kN.m is the sum of the moments of each support joint. Joint 1 - -17,9 kN.m Joint 2 - -19,3 kN.m Joint 3 - -19.3 kN.m

    Triangular steel column

    Dear colleagues, My apologies for taking so long to answer your questions and thank you all for the effort and consideration in trying to find a valid answer for my thread. First of all let me clarify the acronym FEM. As you well understood it means Finite Element Model (never thought it will...

    Triangular Steel Column

    Dear colleague Hokie66! Thank you for aknowledge my thread so fast. In the meantime I solve my problem. I just wanna let you know that your interpretation and your considerations were 100% correct. I was doing a wrong interpretation thereof. My apologies for my poor technical english...

    Triangular steel column

    Hello! I´m testing a FEM of a triangular column with 16.5m height which will hold a publicity screen on the top. For the triangular column I used on the edges of the triangule tubes D244.4x5.4 and between them steel plates S275 with 10mm thickness. The edges have a distance between them of 1m...

    Natural frequency of expansion joints

    Hi Vibac! Did you had any answer for your thread besides this forum? Can you explain me how do you calculate the mass on a certain point of a structure and how do you get its own frequency. Tks

    Periodic Loading

    ...in each period of time of the functions, or it was just randomly chosen? Ex: For function 1 at point b at 0,0625sec does the software assume P(t)*Force(k)? 2- Defining the Load Cases, why do we multiply the period of each one of the functions by 100? For this especific example, the mass...

    Non-linear wind analysis

    Dear colleagues, I need to create a wind analysis on a column with 16 meters height. It will hold on the top a publicity plate with 6m width per 4.5m height. At this moment I´m able to insert on my model static loads from the dynamic analysis provided on the regulation book. This loads already...

    Composite slab

    Hello sdz, I understand that they might be basic for your knowledge, but please understand that not all of us work in the same areas and time to time we have to work with new concepts. Unfortunetly I don´t have anyone in my work with knowledge in composite sections to discuss this or other...

    Composite slab

    rapt and hokie66, My apolögies if I wasn´t clear enough explaining my doubt and thank you for your time. My doubt was clear by the answers of both of you. Sincerely agps PS - Can you advise me any documentation about the subject?

    Composite slab

    hokie66, Thank you for your answer. Can you please explain in a different way. Although I understood your explication I couldn't understand completly your conclusion. PS - I refered to beff as effective "span". I ment "widht". Tk you

    Composite slab

    rapt, Thank you for your answer. Actually I´m doing hand calculation for this case but I´ll use your advise to cross results from hand calculation to FEA. I didn´t explain myself well but my question is very simple: When you try to find out the 'beff' (effective span) in composite slabs for...

    Composite slab

    In that case (lost formwork ´cause rusting), how to analyze the reinforcement between the beams??? Because what I understand from you is that initially it´s a composite section but in a long term will become a normal concrete reinforced slab. How to check the reinforcement in the middle of the...

    Composite structures software

    Hello! I wonder if someone can give me an advice about a software that calculates composite structures (slabs; beams and columns). I´ve been doing this calculation by hand with the help of Excel and I´m now looking for something faster. I don´t need a very detailed software, I just want to...

    Composite slab

    Dear coleagues! I´m calculating a composite slab with a Zinc plate below. How can I get the moments on the slab between the "beff"? Should I consider it as one or should I calculate the metalic beam and the concrete slab (between beff) as separated elements? I´m using EuroCode 4 for this. I...
