    How can I get rid of free edges

    Ha! That's exactly what happened! Thank you. I don't know femap but I thought overlapping nodes will be automatically merged during analysis. Thanks again.

    How can I get rid of free edges

    I'm new to femap and I'm modelling a pedestrian steel crossing all as plates. I have tried "stitch" and "NonManifold Add" and I couldn't get rid of the free edges. All surfaces have consistent mesh and nodes along their connection, but I couldn't figure out what the problem is.

    How to Align Columns with the Edge of the Slab Without Affecting the Facade Line?

    In Eurocode 8 seismic design for medium ductility, the center of the beam and column is limited to column width at the connection divided by 4 (b/4). (you can't just move the beam to the extreme edge of the column unless you satisfy b/4 ). That's, put the beam at the center of the column and you...

    Thickness of seismic RC Wall

    The same thing for the other one too but, that one is on the top right in red. I'm not sure about the fire escape part (I have to ask but looks like it is) regardless the architect doesn't want steel staircase and it has to be cast in situ concrete.

    Thickness of seismic RC Wall

    thank you for your response. 40cm is AR limit but in order to limit span/20 requirement, I was forced to give it 70cm due to code limit. (minimum thickness of wall for medium ductility class in eurocode is max of 0.15m or span/20). If I'm not expected to satisfy that and provide low ductility 20...

    Thickness of seismic RC Wall

    I have a wall in a seismic area that is part of a building and should satisfy the following eurocode provision. The wall supports a stair and the beginning and end of the stair is connected to the RC frame system and floor diaphragm. The wall height is 14m (4 floors each 3.5m center to center...

    What is the general thing to do for a construction on landslide area

    I have an existing structure (belt conveyors and its pier and footings, both steel and RC). It transports materials from downstream (near river) on a very steep slope. Previous geotech investigation found out that top layer is basaltic and the lower one is conglomerate. Their conclusion is there...

    how to create meshed shell/surface created by three half circles

    the top surface is a tensioned surface between the arcs and the lower part is a curved downward dome . I don't have a parameter for the curved part. (other than the radius of the projected curves (the two arcs at 60°). But I will have a smooth transition between these two. (a fitting curve here)...

    how to create meshed shell/surface created by three half circles

    Sorry I know its disrespectful to ask a question and be silent. I apologize but I didn't know how to respond. 1. The top level of my so called "dome" and the half circle are at the same elevation so if i try to cut the sphere with the curve (beams) all of the top surface will be removed (for...

    copy load combinations in etabs

    go to your original model folder and find a file with an extension name of $et and open it. Search "LOAD CASES" and start from $ LOAD CASES up to the end of $ LOAD COMBINATIONS (not the start but the end of load combination) paste it (overwrite) it to your newer $et file. In case you make...

    how to create meshed shell/surface created by three half circles

    Yes, I couldn't do that for the same reason you said. The next question will be how to create that curved surface( the part to be removed) as it is, in which I don't know how to do that. Even after that I don't think I could have all the meshes have a node at the curved edge in which I have a...

    how to create meshed shell/surface created by three half circles

    No its not. Originally, those three circles were ellipses. (the major and minor radius of the ellipse are nearly identical that's why I wanted to simplify). I'm a Structural Engineer and this shape is given to us from the Architects. Those three Ellipses represent a support structure (beam) and...

    how to create meshed shell/surface created by three half circles

    I don't know if this belongs here but, I want to create a shell structure created by three half circles vertically rotated at 60°. (see attached image). So, is there any easy way/tool to create this meshed shell? (I will use it elsewhere for complete structural analysis.) So far I have tried...

    Simply supported two way slab definition

    This might be silly but, me and my friend have different understandings. Is simply supported two slab a. discontinuous at all four edges only or b. if the shorter direction is simply supported and longer direction continuous, the panel is classified still as simply supported we're using...
