Raised floor ni a load-bearing capacity gaw, arung arai, npawt nhpang, hkrang shapraw ai lam ni zawn re ai lam ni hta hkan nna shai hkat nga ai. Madung hku nna, common concrete raised floor ni gaw n-gun ja ai lit-hkap la lu ai atsam nga ai rai nna, lit kaba ni hpe hkam sharang lu ai.
Lit - hpai lu ai atsam hpe sawk sagawn ai:
1. Material gaw lit-hkai lu ai atsam hpe hkra machyi shangun ai: Rawt jat ai npu a lit-hkai lu ai atsam gaw madung hku nna shi a material hta madung nga ai. Concrete hte sharawt tawn da ai npu ni gaw, concrete hkum nan a n-gun kaba ai majaw, lit -hkam lu ai atsam kaja nga ai. Kaga hpun hte n-gang zawn re ai arung arai ni hpe mung sharawt tawn da ai npu ni hpe galaw na matu lang mai ai, raitim shanhte a lit-hkap la lu ai atsam gaw concrete hte shingdaw yang n bung chye ai.
2. Structural design a ahkyak ai lam: Arung arai ni hta n-ga, sharawt tawn da ai npu a structure design mung shi a lit-hkap la lu ai atsam hpe hkra machyi shangun ai ahkyak ai lam langai rai nga ai. Hpa majaw nga yang, npu hpe n-gun dat ai shaloi, grai n-gun n rawng ai (sh) hkra machyi ai lam n byin na matu, htuk manu ai hkrang masa gaw, n-gun n rawng hkra galaw ya ai. Design galaw ai ni gaw, npu na lit-hkap la lu ai atsam hpe jat wa hkra, beam, column, hte kaga npawt nhpang ni hpe lang na matu myit yu na re.
3. Lit amyu ni hpe myit yu ai lam: Raised floor a load-bearing capacity hpe mung load amyu gaw hkra machyi shangun ai. Static lit, dynamic lit, hte concentrated lit zawn re ai lit amyu myu gaw, npu na lit-hkap la lu ai atsam a matu ra kadawn ai lam n bung ai. Design gaw, npu gaw myit mada da ai load{5}}bearing ra kadawn ai lam ni hpe hkan sa lu na matu, teng sha jai lang ai masa hpe tup hkrak myit yu ra ai.
