求助 钢框架的端板连接的有限元分析
下面是我的命令流，求高手帮我看看 为什么就solve不了的呢 ？/prep7
!定义参数
hc=300 !柱截面高度
bc=300 !柱截面宽度
tcf=15 !柱翼缘厚度
tcw=10 !柱腹板厚度
lc=1800 !柱构件伸出长度
hb=244 !梁截面高度
bb=210 !梁截面宽度
tbf=11 !梁翼缘厚度
tbw=7 !梁腹板厚度
lb=1500 !梁构件伸出长度
hd=400 !端板高度
bd=250 !端板宽度
td=10 !端板厚度
miu=0.4 !板间抗滑移系数
lbt=tcf+td !螺栓杆长度
dbt=25 !螺栓杆直径
dbth=30 !螺栓头和螺母直径
lbth=12.5 !螺栓头厚度
dh0=dbt+2 !螺栓孔直径
preten=155000 !螺栓施工预拉力
