M + R yog sib npaug rau 2J rau kev txiav txim siab hauv statically trusses, thiab M + R yog ntau dua 2J rau sab hauv statically indeterminate trusses, qhov twg M yog tag nrho Tus naj npawb ntawm cov tswv cuab hauv lub truss, R yog tag nrho cov tsis paub cov tshuaj tiv thaiv, thiab J yog tag nrho cov pob qij txha hauv lub truss.

Yuav ua li cas koj thiaj nrhiav tau qhov tsis txaus ntseeg zoo li qub?

Determinate Structure: yog qhov sib npaug sib npaug yog txaus los tshuaj xyuas rau cov tsis paub rog, Cov qauv tau hais kom txiav txim siab. Yog tias qhov sib npaug sib npaug tsis txaus los txheeb xyuas cov qauv rau cov tsis paub lub zog, cov qauv tau hais tias yog qhov tsis txaus ntseeg.

Dab tsi yog qib ntawm qhov tsis txaus ntseeg zoo li qub?

Tus DEGREE OF STATIC INDETERMINACY (DSI) yog tus naj npawb ntawm cov tsis muaj zog hauv cov qauv … Tsis paub zoo li qub (kev tshwm sim thiab lub zog sab hauv) thiab tus lej ntawm qhov sib npaug zoo li qub (kev sib npaug sib npaug).

Dab tsi yog qhov kev txiav txim siab zoo li qub ntawm cov nqaj ruaj khov?

Rau cov txheej txheem dav dav ntawm kev thauj khoom, lub nqaj ruaj khov yog statically txiav txim siab rau qib peb. Rau ntsug loading, ib tug ruaj beam yog statically indeterminate rau qib thib ob. Lub beam yog statically indeterminate mus rau qib peb ntawm cov txheej txheem ntawm kev thauj khoom.

Dab tsi yog qhov zoo li qub thiab kinematic indeterminacy?

Kev sib npaug sib npaug • Thaum lub cev nyob hauv qhov sib npaug, tsis muaj kev txhais lus lossis kev sib hloov tshwm sim nyob rau hauv ib qho kev taw qhia. … • Txij li thaum tsis muaj kev txhais lus, cov txiaj ntsig ntawm lub zog ua rau lub cev yuav tsum yog xoom.
