This underscores the significance of using reliable models. -The video demonstrates the initial modeling steps, including creating contours and applying loads, showcasing how to efficiently set up a structural model using simple tools. -Different material properties, such as concrete elasticity and reinforcement characteristics, are crucial for proper modeling. Understanding these properties helps in achieving a realistic simulation of structural behavior. 36:32 The video demonstrates the process of generating a mesh for concrete structures, focusing on the creation of specific elements and reinforcement configurations. The speaker highlights the importance of mesh size and element properties for accurate modeling. -The speaker discusses the selection of element sizes and properties, emphasizing the use of nonlinear shape functions for improved accuracy in modeling. This is crucial for realistic simulations. -The video outlines the process of applying boundary conditions and loads, detailing the fixed boundaries at column tips and vertical loads at the top of beams. This step is essential for realistic analysis. -Lastly, the speaker explains the setup for analysis, including naming the analysis type and controlling output parameters to ensure correct interpretation of results. This is vital for understanding structural behavior. 48:38 Advanced modeling techniques are essential in predicting the behavior of concrete structures under various conditions. These models enable engineers to analyze and mitigate potential failure points effectively. -The use of numerical and experimental tests in this research enhances understanding of the structural integrity of reinforced concrete under progressive collapse scenarios. Detailed models provide valuable insights for engineers. -3D modeling techniques, including total strain crack models, allow for accurate predictions of cracking patterns in concrete structures. This is crucial for the design of robust construction elements. -Investigating the influence of transverse steel reinforcement on cracking prediction helps improve the durability of concrete walls and slabs. This is particularly important in multi-story building designs. 58:33 The discussion revolves around the application of nonlinear creep in structural analysis, particularly in concrete and timber sections. Various methods for modeling loads and stresses are highlighted, showcasing their flexibility in engineering design. -Nonlinear creep can be defined using a set of creep curves based on loads applied, allowing engineers to analyze strain behaviors effectively. This is crucial for accurate structural modeling. -Applying pressure loads or distributed forces in modeling can yield similar results, giving engineers the choice to use the most convenient method for their design. This flexibility enhances modeling precision. -The importance of mesh quality in modeling is emphasized, as finer meshes can lead to more accurate results in areas of interest. This helps ensure convergence in structural analysis. Generated by sider.ai

Hi, I am using midas 2022 version. When ever I use scroll to zoom in our zoom out I get option to zoom in or out just by moving mouse backwards or forwards and afterwards I have to middle click to exit "the zoom" mode. A bit annoying to be honest. Is there any way to turn this off?

Thanks for your video!! It's very helpful for engineers to learn and understand how to model more exactly bridge works on software. However, i have little bit confuses as below: If i applied Small displacement mode for completion model of stay cable bridge to get initial element forces, and took these values as equilibrium element nodal forces of large displacement mode of backward analysis model, what should i do with initial forces for geometric stiffness? Ignore it or take it as input data of backward model? If necessary, how can i take? Thanks for your helping again.

it is better if u add ur voice

How does the road or I guess you call it the deck get anchored to ground where the bridge meets land? I'm a total amateur I'm trying to build a small model of one.

hi, for this tutorial. Can share the CAD file as i'm learning this new software.

Hai medam, in material data,what is DB.

Can you share me this file, thanks so much

😮

can we plot support reactions for time history analysis in midas gen

Please provide the ppt and design of tub girder bridge

Material and section properties?

Thank you, Mr. Rudra! Such a good and helpful expositon!

can u show me how to make the pier? thanks slebew

Thank You.

Can you please tell me how to install midas civil crack version

thanks for the video, just FYI at 4:35 to 4:44, automatic jumped a bit,

Can I view the deck slab as solid rather than transparency view?

Can I view the deck slab as solid rather than transparency view?

It's not that clear how you created nodes on the steel tub girder sections, could you please explain me more on that? As you mentioned in the video, since those tub girders are represented by single nodes, how do we create nodes on the surfaces of tub girder? If there's a link to video doing this or even a file done in Midas it would be great if you forward it. Thanks!!

You have activated the PS on the same day of girder concreting.

Such an analysis seems to be far away from the real soil structure interaction.

Hi in the generated excel sheet, the value of modulus of elasticity of concrete is not permissible.

Why do I get the wrong message"No element to Extract", in the step of Mesh check.

in case, if the structure timber changes to concrette slab with inclinated, what the process analisis about that, thank u
