怎么样在三维壳单元上施加水平拉力

如图所示，下部是混凝土，上面的壳单元是用来模拟碳纤维布的，想在红圈处施加水平拉力，但是数据检查时总会提示错误：Surface assembly_surf-25 includes edges. Except for shell edge loading, surfaces which include edges cannot be used with *dsload, *dsflux, *sfilm, *sradiate, *dsflow, *sflow, *dsecharge, *dsecurrent, *simpedance or *incident wave.请问到底要怎么施加呢？还有壳单元和混凝土单元完全粘结是不是用Tie把两个面绑定在一起就行啊？或者说共用节点用怎么操作。求大神~~~
