さくっとFEMの結果の検証など、パリティチェックに重宝しています。 あとは拘束条件にバネ支持が追加されるということ無しです。任意の位置にバネ定数（並進バネであればkN/mなど、回転バネであればkNm/radなど）で入力して相持ち構造の効果を確認できるようになると更に使い勝手が良いです。 ※バネ定数 :入力位置の変位や回転角に応じて、反力やモーメントを生じさせるために入力する。

Would be great if there’s an option for different EI at different span.

If you are mechanical, civil engineer or chemical engineer or some, you should get this app. This is really accurate and compact to use at site and office. I really appreciate for this app to the developer. You are my HERO.

Great sanity check software before delving into a solid model evaluation

Kinda klunky interface. The calculator layout is poor. Calculator needs means of entering scientific notation. Missing aluminum extrusions. Should have a way to favorite beam shapes and add user defined ones. I prefer scientific notation normalized to be x.xx x10^x not xxx.x x10^x Not sure why 10x length limitation.

it should have angle for better experiment

Great job on this beautifully designed app! I just wish it had smaller shapes built in, down to 1/2 square steel tube. Or, maybe provide a way for user defined shapes to be added? Thanks!

OK not meaning to put the dev down as this is a nice approach but I think the dev should have spent more time making the app workable than playing with the interface. The app is so called "version 5.0". One would assume from this it would have passed through four major iterations to get to this point. The app feels like beta release 0.9. The following are missing. 1. Save and file functions 2. Undo and redo 3. A "help" or tutorial. Also what would be nice would be the ability to design or draw beam sections instead of using the only ones offered. All that is provided is a database of standard sections downloaded off the internet, this would have been provided by version 3 or 4. The app feels like an engineer grad student trying to show off the engineering knowledge. Any of the five star reviews are either friends of the dev or purchasers of previous versions who are happy to see progress. If I have misrepresented the dev and invite them to contact me and I will revise my review.

I just wanted to let you guys know that there is a flaw in the calculation of the theta value! It is 10 Times smaller than the actual value. There must be a bug for that output.

Love the app, great visual interface...but why not 50 and 65 KSI steel? Today almost all structural steel is grade 50 KSI....this application is now limited to 36 KSI steel design. To make application useful it needs that upgrade.
