某省抗震規(guī)程附錄磚房抗震墻基準面積率

PAGEPAGE111附錄A磚房抗震墻基準面積率A.0.1多層磚房抗震墻基準面積率，可按下列規(guī)定取值：1住宅、單身宿舍、辦公樓、學(xué)校、醫(yī)院等，按縱、橫兩方向分別計算的墻段基準面積率，當樓層單位面積重力荷載代表值gE為12KN/㎡時，可按表A.0.1-1至A.0.1-3采用；當樓層單位面積重力荷載代表值為其他數(shù)值時，表中數(shù)值可乘以gE/2。2按縱、橫兩方向分別計算的樓層抗震墻基準面積率，承重墻可按表A.0.1-2至3采用；自承重墻宜按表A.0.1-1數(shù)值的1.05倍采用；同一方向有承重墻和自承重墻或砂漿強度等級不同時，可按各自的凈面積比相應(yīng)轉(zhuǎn)換為同樣條件下的數(shù)值。3僅承受過道樓板荷載的縱墻可當做自承重墻；支承雙向樓板的墻體，均宜做為承重墻。A.0.2底層框架和底層內(nèi)框架磚房的抗震墻基準面積率，可按下列規(guī)定取值：1上部各層，均可根據(jù)房屋的總層數(shù)，按多層磚房的相應(yīng)規(guī)定采用。2底層框架磚房的底層，可取多層磚房相應(yīng)規(guī)定值的0.85倍；底層內(nèi)框架磚房的底層，仍可按多層磚房的相應(yīng)規(guī)定采用。A.0.3多層內(nèi)框架磚房的抗震墻基準面積率，可取按多層磚房相應(yīng)規(guī)定值乘以下式計算的調(diào)整系數(shù)：（A.0.3）式中——層基準面積率調(diào)整系數(shù)；——層的位置調(diào)整系數(shù)，按表A.0.2采用；、、、、、——按國家標準《建筑抗震設(shè)計規(guī)范》GBJ11第7章的規(guī)定采用。表A.0.1-1抗震墻基準面積率（自承重墻）墻體類別總層數(shù)n驗算層數(shù)i砂漿強度等級M0.4M1M2.5M5M10一層10.02190.01480.00950.00690.0050二層20.02920.01970.01270.00920.006610.03660.02560.01720.01290.0094橫三層30.03280.02210.01430.01040.0075墻1～20.04780.03430.02360.01800.0133和四層40.03500.02360.01520.01110.0080無30.05130.03580.02400.01790.0131門1～20.05770.04180.02930.02250.0169窗五層50.03650.02460.01590.01150.0083縱40.05500.03840.02570.01920.0140墻1～30.06560.04840.03430.02670.0202六層60.03750.02530.01630.01190.008550.05750.04020.02700.02010.014740.06880.04900.03370.02550.01901～30.07340.05430.03890.03050.0282墻體平均壓應(yīng)力力（Mpaa）0.06（n--i+1))一層10.01980.01370.00900.00670.0032二層20.02630.01830.01200.00890.006410.03220.02280.01570.01200.0089三層30.02980.02050.01350.01010.0072每1～20.04110.03010.02130.01640.0124開四層40.03180.02190.01440.01060.0077間30.04500.03200.02210.01670.0124有1～20.04990.03620.02600.02030.0155一五層50.03310.02280.01500.01110.0080個40.04820.03440.02370.01790.0133窗1～30.05730.04230.03030.02380.0183縱六層60.03410.02350.01550.01140.0083墻50.05050.03600.02480.01880.013940.05940.04300.03040.02340.01771～30.06410.04750.03450.02710.0209墻體平均壓應(yīng)力力（Mpaa）0.09（n--i+1))表A.0.1-2抗震墻基準面積率（承重橫墻）墻體類別總層數(shù)n驗算層數(shù)i砂漿強度等級M0.4M1M2.5M5M10一層10.25800.01790.01180.00880.0064二層20.34400.02380.01580.01170.008510.04130.02960.02050.01560.0116無三層30.03870.02680.01780.01320.00951～20.05280.03880.02750.02130.0161門四層40.04130.02860.01890.01400.010230.05790.04140.02870.02160.0163窗1～20.06280.04640.03350.02630.0241五層50.04300.02970.01970.01470.0106橫40.06200.04440.03080.02340.01741～30.07110.05320.03880.03070.0237墻六層60.04420.03050.02030.01510.010950.06490.04650.03230.02450.018240.07620.05540.03930.03040.02301～30.07900.05920.04350.03470.0270墻體平均壓應(yīng)力（MPa）0.10（n--i+1))一層10.02450.01710.01150.00860.0062二層20.03260.02280.01530.01140.0085有10.03860.02790.01960.01500.0112三層30.03670.02550.01720.01290.0094一1～20.04810.03630.02600.02040.0155四層40.03910.02730.01830.01370.0100個30.05410.03900.02740.02100.01571～20.05810.04330.03140.02490.0192門五層50.04080.02850.01910.01420.010440.05800.04180.02940.02250.0169的1～30.06580.04930.03630.02890.0225六層60.04180.02930.01960.01460.0107橫50.06070.04380.03080.02360.017740.07080.05180.03720.02890.0221墻1～30.07290.05480.04060.03260.0255墻體平均壓應(yīng)力（MPa）0.12（n--i+1))表A.0.1-3抗震墻基準面積率（承重縱墻）墻體類別總層數(shù)n驗算層數(shù)i砂漿強度等級M0.4M1M2.5M5M10一層10.02230.01580.01080.00810.0060二層20.02980.02110.01350.01080.008010.03460.02530.01800.01390.0106每三層30.03350.02370.01620.01220.0090開1～20.04350.03250.02350.01870.0144間四層40.03570.02530.01730.01300.0096有30.04840.03540.02520.01950.0148一1～20.05130.03840.02830.02260.0176個五層50.03720.02640.01800.01360.0100門40.05190.03790.02700.02090.0159或1～30.05800.04370.03240.02610.0205一六層60.03830.02710.01850.01400.0108個50.05440.03970.02830.0219
