某省抗震规程附录砖房抗震墙基准面积率

PAGEPAGE111附录A砖房抗震墙基准面积率A.0.1多层砖房抗震墙基准面积率，可按下列规定取值：1住宅、单身宿舍、办公楼、学校、医院等，按纵、横两方向分别计算的墙段基准面积率，当楼层单位面积重力荷载代表值gE为12KN/㎡时，可按表A.0.1-1至A.0.1-3采用；当楼层单位面积重力荷载代表值为其他数值时，表中数值可乘以gE/2。2按纵、横两方向分别计算的楼层抗震墙基准面积率，承重墙可按表A.0.1-2至3采用；自承重墙宜按表A.0.1-1数值的1.05倍采用；同一方向有承重墙和自承重墙或砂浆强度等级不同时，可按各自的净面积比相应转换为同样条件下的数值。3仅承受过道楼板荷载的纵墙可当做自承重墙；支承双向楼板的墙体，均宜做为承重墙。A.0.2底层框架和底层内框架砖房的抗震墙基准面积率，可按下列规定取值：1上部各层，均可根据房屋的总层数，按多层砖房的相应规定采用。2底层框架砖房的底层，可取多层砖房相应规定值的0.85倍；底层内框架砖房的底层，仍可按多层砖房的相应规定采用。A.0.3多层内框架砖房的抗震墙基准面积率，可取按多层砖房相应规定值乘以下式计算的调整系数：（A.0.3）式中——层基准面积率调整系数；——层的位置调整系数，按表A.0.2采用；、、、、、——按国家标准《建筑抗震设计规范》GBJ11第7章的规定采用。表A.0.1-1抗震墙基准面积率（自承重墙）墙体类别总层数n验算层数i砂浆强度等级M0.4M1M2.5M5M10一层10.02190.01480.00950.00690.0050二层20.02920.01970.01270.00920.006610.03660.02560.01720.01290.0094横三层30.03280.02210.01430.01040.0075墙1～20.04780.03430.02360.01800.0133和四层40.03500.02360.01520.01110.0080无30.05130.03580.02400.01790.0131门1～20.05770.04180.02930.02250.0169窗五层50.03650.02460.01590.01150.0083纵40.05500.03840.02570.01920.0140墙1～30.06560.04840.03430.02670.0202六层60.03750.02530.01630.01190.008550.05750.04020.02700.02010.014740.06880.04900.03370.02550.01901～30.07340.05430.03890.03050.0282墙体平均压应力力（Mpaa）0.06（n--i+1))一层10.01980.01370.00900.00670.0032二层20.02630.01830.01200.00890.006410.03220.02280.01570.01200.0089三层30.02980.02050.01350.01010.0072每1～20.04110.03010.02130.01640.0124开四层40.03180.02190.01440.01060.0077间30.04500.03200.02210.01670.0124有1～20.04990.03620.02600.02030.0155一五层50.03310.02280.01500.01110.0080个40.04820.03440.02370.01790.0133窗1～30.05730.04230.03030.02380.0183纵六层60.03410.02350.01550.01140.0083墙50.05050.03600.02480.01880.013940.05940.04300.03040.02340.01771～30.06410.04750.03450.02710.0209墙体平均压应力力（Mpaa）0.09（n--i+1))表A.0.1-2抗震墙基准面积率（承重横墙）墙体类别总层数n验算层数i砂浆强度等级M0.4M1M2.5M5M10一层10.25800.01790.01180.00880.0064二层20.34400.02380.01580.01170.008510.04130.02960.02050.01560.0116无三层30.03870.02680.01780.01320.00951～20.05280.03880.02750.02130.0161门四层40.04130.02860.01890.01400.010230.05790.04140.02870.02160.0163窗1～20.06280.04640.03350.02630.0241五层50.04300.02970.01970.01470.0106横40.06200.04440.03080.02340.01741～30.07110.05320.03880.03070.0237墙六层60.04420.03050.02030.01510.010950.06490.04650.03230.02450.018240.07620.05540.03930.03040.02301～30.07900.05920.04350.03470.0270墙体平均压应力（MPa）0.10（n--i+1))一层10.02450.01710.01150.00860.0062二层20.03260.02280.01530.01140.0085有10.03860.02790.01960.01500.0112三层30.03670.02550.01720.01290.0094一1～20.04810.03630.02600.02040.0155四层40.03910.02730.01830.01370.0100个30.05410.03900.02740.02100.01571～20.05810.04330.03140.02490.0192门五层50.04080.02850.01910.01420.010440.05800.04180.02940.02250.0169的1～30.06580.04930.03630.02890.0225六层60.04180.02930.01960.01460.0107横50.06070.04380.03080.02360.017740.07080.05180.03720.02890.0221墙1～30.07290.05480.04060.03260.0255墙体平均压应力（MPa）0.12（n--i+1))表A.0.1-3抗震墙基准面积率（承重纵墙）墙体类别总层数n验算层数i砂浆强度等级M0.4M1M2.5M5M10一层10.02230.01580.01080.00810.0060二层20.02980.02110.01350.01080.008010.03460.02530.01800.01390.0106每三层30.03350.02370.01620.01220.0090开1～20.04350.03250.02350.01870.0144间四层40.03570.02530.01730.01300.0096有30.04840.03540.02520.01950.0148一1～20.05130.03840.02830.02260.0176个五层50.03720.02640.01800.01360.0100门40.05190.03790.02700.02090.0159或1～30.05800.04370.03240.02610.0205一六层60.03830.02710.01850.01400.0108个50.05440.03970.02830.0219
