为此，本文着重对受集中荷载的外贴碳纤维或钢板条带的钢筋混凝土加固双向板的受力性能进行了试验研究。

So far, a great deal of research work has been done for RC beams strengthened by bonded CFRP or steel plate, but only rather little for two-way RC slabs.

为此，本文着重对受集中荷载的外贴碳纤维或钢板条带的钢筋混凝土加固双向板的受力性能进行了试验研究。

Therefore, experimental study on the behavior of the strengthened two-way slabs bonded with strips made of CFRP or steel and subjected to a central patch load was carried out by the authors.
