密肋壁板结构是由预制的密肋复合墙板、现浇的隐形框架和楼板组合而成的一种具有独特构造特点的新型复合结构体系。根据密肋壁板结构体系的基本特点，引入耗能减震技术，结合极低屈服点钢材的特性，将结构中部分密肋复合墙板中的填充砌块置换成极低屈服点钢板，利用极低屈服点钢板耗散地震能量，实现对结构的耗能减震控制。建立了密肋壁板结构耗能减震控制体系的非线性动力分析模型，通过算例对耗能减震控制体系进行了地震响应分析，探讨了极低屈服点钢的耗能减震效果。计算结果表明，在结构中布置少量的极低屈服点钢板就能取得明显的减震效果，从而为密肋壁板结构提供一种适合这种结构构造特点的简单有效的耗能减震措施。

Multi-ribbed slab structure (MRSS)is a new type of composite structure with specific characteristics,it is composed of prefabricated multi-ribbed composite wall slab,cast-in-place floor slab and cast-in-suit concealed outer frame.According to the basic components and construction characteristics of MRSS,the ultra-low yield strength steel panels were used in multi-ribbed composite wall slabs.The seismic response control of multi-ribbed slab structures using ultra low yield strength steel was explored.The nonlinear dynamic time-history analysis of a MRSS aseismic control system under horizontal earthquake waves was carried out.The earthquake response and energy dissipation mechanism of the controlled structure were investigated.The effects of vibration reduction of the ultra-low yield strength steel panel were discussed.The computing results showed that the ultra-low yield strength steel panel has obvious seismic mitigation effect, it provides a simple and effective seismic energy dissipation measure for multi-ribbed slab structures.
