Ua raws li qhov no, dab tsi yog qhov tseem ceeb ntawm tus choj?

Cov cov khoom tseem ceeb ntawm tus choj yog lub hauv paus, substructure, thiab superstructure. Txhua qhov chaw tseem ceeb no muaj lwm yam ntu hauv lawv. Piles thiab pawg kaus mom yog tsim los ua lub hauv paus ntawm lub tus choj.

Tsis tas li ntawd, dab tsi ua rau tus choj ruaj khov? Daim duab peb sab ua rau cov qauv muaj zog vim tias kev ua haujlwm tawm ntawm compression thiab nro. Daim duab peb sab ntawm qhov chaw nres nkoj tus choj yog nyob rau hauv arch vim lub arch yuav tsum muaj zog nyob rau hauv thiaj li yuav khaws cov tus choj nce thiab nqa lub load. Lub koov muaj txiaj ntsig zoo vim tias nws hloov pauv lub thauj khoom tsis yog tsom lub nra ntawm ib qho chaw.
