摘要
对于中强冷轧８００ＭＰａ级带肋钢筋预应力空心板在各种不同的集中荷载作用下的动力特性进行了全面的试验研究。文中给出了板的自振特性、阻尼比和动力刚度在冲击过程中的变化规律。对冲击荷载作用下板在强度、变形、裂缝、地震响应等方面的特性进行了讨论。
The dynamic behaviour of a new reinforced concerte hollow plate using the medium strength(800 MPa yield strength)ribbed bar as prestressed wire has been studied experimentaly under various concentrated impact loads.The test results on the inherent characteristics,frequency,damping,dynamic rigidity etc.are presented.Meanwhile the important points in respect to the strength,deformation,cracking under impact loads and earthquake response of plate have discussed.
