［摘要］介绍了新型的预应力混凝土框架体系——自控耗能无粘结部分预应力混凝土（UPPC）框架的基本形式及其受力机理。对自控耗能UPPC框架的核心构件——自控元件的基本构造和施工工艺做了说明，对自控元件的铸铁部分、变形盒部分以及自控元件整体进行了力学性能试验。试验结果表明：1）自控元件的破坏形式为脆性破坏，满足在罕遇地震下自控元件达到其承载力阈值时突然破坏，自控耗能UPPC框架形成安全的梁铰耗能机制［1］的要求；2）碳纤维布与铸铁的复合使用，能显著提高自控元件的极限承载力，同时能达到减小自控元件尺寸、减轻其重量的目的，便于自控元件在工程中的应用。

Abstract： The form and the stress mechanism of self-control energy dissipation UPPC frame—a new prestressed concrete frame system were introduced. Instructions about the design and manufacture process of self-control component—the core part of self-control energy dissipation UPPC frame were given. Mechanical performance experiment of self-control component and it’s were carried out. The experimental results show that: 1) the failure mode of self-control component is brittle failure, which is conform to the requirements: self-control component suddenly destroyed when reaches its carrying capacity, then energy dissipation UPPC frame would form the beam hinge mechanism under severe earthquake ; 2) the compound using of carbon fiber sheet and cast iron can significantly improve the ultimate bearing capacity of self-control component, at the same time reducing the weight of self-control component and its size, which is benefit for the use of self-control component in engineering.

Keywords： self-control component；self-control energy dissipation frame；seismic design
