Khoov:Tensile thiab compressive kev ntxhov siab ua ke los tsim lub sijhawm khoov. Kev ua tsis tiav los ntawm kev khoov yog tshwm sim thaum lub zog tensile thiab compressive zog tshaj qhov kev txwv ntawm cov nqaj.
Buckling:Thaum muaj kev hloov pauv sai sai vim qhov kev ntxhov siab torsional ua rau lub nqaj deform. Qhov no feem ntau tshwm sim thaum taw qhia ua ke. Flanges yog qhov tseem ceeb rau kev txiav txim siab.
Deflection:Deflection yog tus nqi ntawm cov qauv beam yuav hneev lossis khoov thaum lub thauj khoom siv rau qhov ntev ntawm nws. Tus nqi ntawm deflection tuaj yeem txo qis los ntawm kev siv cov tuab txaus ntawm cov hlau rau cov qauv nqaj.
Tension:Beams yuav raug rub thiab ncab zog. Kev xaiv lub web thickness yuav pab txo tau txoj hauv kev ntawm rippling los yog buckling.
Kev vibration:Kev siv cov compressors, twj, thiab cav nyob rau ntawm qhov chaw ua rau muaj kev vibration. Txhawm rau tiv thaiv qhov kev quab yuam no, yuav tsum siv cov kab nrib khov thiab siab dua.
Qhov tsis yog-uniform cross-section ntawm tus qauv nqaj yog tsim los rau deflect los yog khoov nyob rau hauv ntau dhau load as opposed to buckling.
