必须保证每个截面的关键点号相同，而且为保证生成的准确性，应尽量的使得关键点有足够多的数目。
2、要对截面进行面积分块，并指定各线段的段数，这样才能做出规整的箱梁截面网格划分，也就保证了变截面箱梁桥各截面的网格模式相同，建议对于变化急剧的两边截面应使得线足够的短。
并不是划分越密越可能成功，而是线越短越可能成功3。
通过梁节段两端对应的截面建立taper截面，定义好桥的线形后，指定每段线对应的taper截面。
4、可以用slist命令查看生成截面的性质，加深对secread 命令的理解以下例进行说明：Ⅱ-Ⅱ截面图Ⅰ-Ⅰ截面图全梁1/2图示Ⅰ-Ⅰ截面命令流finish/clear/prep7k,1k,2,2750k,3,3350,2400 k,4,5450,2750 k,5,6700,2850 k,6,6700,3050 k,7,0,3050k,8,0,280k,9,2359,280k,10,2886,2400 k,11,1836,2750 k,12,0,2750l,1,2l,2,3l,3,4l,4,5l,5,6l,6,7l,8,9l,9,10l,10,11l,11,12l,1,8l,7,12al,all arsym,x,all aadd,1,2 nummrg,all numcmp,all adele,1l,2,9l,13,20l,14,19l,10,3l,1,8al,22,17,25,19 al,25,1,21,7 lcomb,15,20 wpoffs,-5450,2750 wprota,,,90 lsbw,18wpcsys,-1 wpoffs,-3350,2400 wprota,,,90 lsbw,20wpcsys,-1 wpoffs,-2886,2400 wprota,,,90 lsbw,18wpcsys,-1l,15,18l,14,21l,19,22l,7,12al,14,13,18,26 al,18,12,29,27al,29,23,30,28al,30,15,31,20 lcomb,9,10 wpoffs,5450,2750 wprota,,,90 lsbw,6wpcsys,-1 wpoffs,3350,2400 wprota,,,90 lsbw,32 wpcsys,-1 wpoffs,2886,2400 wprota,,,90 lsbw,6wpcsys,-1l,4,11l,3,23l,10,24al,5,4,6,10al,3,6,33,35al,24,35,34,36 al,9,36,32,31 ldiv,16,,,4 ldiv,11,,,4ldiv,2,,,4ldiv,8,,,4l,30,27l,29,26l,28,25l,36,33l,35,32l,34,31al,23,42,49,39 al,49,41,50,38 al,50,40,51,37 al,51,11,22,16 al,24,48,52,45 al,52,47,53,44 al,53,46,54,43 al,54,8,21,2 nummrg,all numcmp,all et,1,82 lesize,1,,,4 lesize,17,,,4 lesize,19,,,4 lesize,7,,,4 lesize,22,,,1lesize,21,,,1lesize,25,,,1 mshape,1,2d mshkey,2 amesh,1 amesh,2 lesize,23,,,1 lesize,42,,,1 lesize,39,,,1 lesize,49,,,1 lesize,41,,,1 lesize,50,,,1 lesize,38,,,1 lesize,40,,,1 lesize,37,,,1 lesize,51,,,1 lesize,11,,,1 lesize,16,,,1 lesize,22,,,1 lesize,24,,,1 lesize,45,,,1 lesize,48,,,1 lesize,52,,,1 lesize,44,,,1lesize,47,,,1lesize,53,,,1 lesize,43,,,1 lesize,46,,,1 lesize,54,,,1 lesize,2,,,1 lesize,8,,,1 lesize,21,,,1 mshape,0,2d mshkey,1 amesh,11 amesh,12 amesh,13 amesh,14 amesh,15 amesh,16 amesh,17 amesh,18 lesize,13,,,2 lesize,26,,,2 lesize,14,,,1 lesize,18,,,1 mshape,1,2d mshkey,2amesh,3lesize,12,,,3 lesize,27,,,3 lesize,18,,,1 lesize,29,,,1 mshape,1,2d mshkey,2 amesh,4 lesize,23,,,1 lesize,29,,,1 lesize,30,,,1 lesize,28,,,1 mshape,0,2d mshkey,2 amesh,5 lesize,30,,,1 lesize,20,,,4 lesize,31,,,1 lesize,15,,,4 mshape,1,2d mshkey,2 amesh,6 lesize,31,,,1 lesize,9,,,4lesize,36,,,1lesize,32,,,4 mshape,1,2d mshkey,2 amesh,10 lesize,35,,,1 lesize,34,,,1 lesize,24,,,1 lesize,36,,,1 mshape,0,2d mshkey,2 amesh,9 lesize,6,,,1 lesize,35,,,1 lesize,3,,,3 lesize,33,,,3 mshape,1,2d mshkey,2 amesh,8 lesize,6,,,1 lesize,5,,,1 lesize,10,,,2 lesize,4,,,2 mshape,1,2dmshkey,2amesh,7secwrite,mybox1主命令流finish/clear/prep7k,5000,7800k,5001,8851k,5002,9899k,5003,10800k,5004,12300k,5005,0l,5000,5001l,5001,5002l,5002,5003l,5003,5004l,5000,5005k,100,8300,4000 k,101,9500,4000 k,102,10000,4000 et,1,beam189mp,ex,1,3.0e10 mp,prxy,1,0.167 sectype,1,beam,meshsecread,mybox1,,,mesh sectype,2,beam,mesh secread,mybox2,,,mesh sectype,3,taper secdata,1,7800 secdata,2,8851et,2,beam189mp,ex,2,3.0e10mp,prxy,2,0.167 sectype,4,beam,mesh secread,mybox2,,,mesh sectype,5,beam,mesh secread,mybox3,,,mesh sectype,6,taper secdata,4,8851 secdata,5,9899et,3,beam189mp,ex,3,3.0e10mp,prxy,3,0.167 sectype,7,beam,mesh secread,mybox3,,,mesh sectype,8,beam,mesh secread,mybox4,,,meshsectype,9,tapersecdata,7,9899 secdata,8,10800et,4,beam189mp,ex,4,3.0e10mp,prxy,4,0.167 sectype,10,beam,mesh secread,mybox4,,,mesh et,5,beam189mp,ex,5,3.0e10mp,prxy,5,0.167 sectype,11,beam,mesh secread,mybox1,,,mesh lesize,1,,,2lesize,2,,,2lesize,3,,,2lesize,4,,,2lesize,5,,,8allsellsel,s,line,,1latt,1,,1,,100,,3 allsellsel,s,line,,2latt,2,,2,,101,,6allsellsel,s,line,,3latt,3,,3,,102,,9allsellsel,s,line,,4latt,4,,4,,102,,10lsel,s,line,,5latt,5,,5,,102,,11lmesh,1,5,1allsellmesh,1,5,1/eshape,1eplot分享 | 评论 | 举报来自：花落无痕的日志你可能还喜欢[视频]《爱情公寓第一季》爆笑片段剪...
