2.11. Qhov feem ntawm cov slab uas ua integrally nrog cov nqaj los tiv thaiv loads yog hu ua Flange ntawm lub T - nqaj los yog L - nqaj . Qhov feem ntawm lub nqaj hauv qab lub flange hu ua Web los yog Rib ntawm lub nqaj . Qhov nruab nrab kab teeb txhawb cov slab hu ua T - kab teeb thiab qhov kawg kab teeb npe as L - kab teeb.
Kuj tseem paub yog, L beam yog dab tsi?
L - nqaj . A nqaj uas seem muaj daim ntawv ntawm ib qho inverted L ; feem ntau muab tso kom nws sab saum toj flange ua ib feem ntawm ntug ntawm ib lub hauv pem teb.
Ib sab saum toj no, dab tsi yog rib ntawm T beam? Cov nqaj muaj flange thiab a rib nyob rau hauv daim ntawv ntawm a T , feem ntau ua los ntawm RC pob zeb lossis hlau yog hu ua T - nqaj . Sab saum toj ntawm Slab uas ua raws li nqaj los tiv thaiv compressive kev nyuaj siab yog hu ua flange. Ib feem uas nyob hauv qab lub slab thiab resists shear stress yog hu ua rib.
Hais txog qhov no, T beams siv rau dab tsi?
A T - nqaj (los yog tee beam ), siv hauv kev tsim kho, yog ib qho kev thauj khoom ntawm cov pob zeb, ntoo lossis hlau, nrog a T -zoo li tus hla ntu. Sab saum toj ntawm T -zoo li tus ntoo khaub lig seem ua hauj lwm raws li ib tug flange los yog compression tswv cuab nyob rau hauv resisting compressive stresses.
Dab tsi yog qhov txawv ntawm I beam thiab AH beam?
Nws tau txais nws lub npe vim nws zoo li ib peev H hla nws hla ntu. Lub H- nqaj muaj flanges dav dua li qhov I- nqaj tab sis kuv- nqaj muaj tapered npoo. Qhov dav yog qhov flange, thiab qhov siab yog Web. Cov qhov sib txawv ntawm ob leeg H- kab teeb thiab kuv- kab teeb yog lub flange los ntawm lub vev xaib sib piv.
