冷轧扭钢筋混凝土连续梁、板塑性调幅设计

冷轧扭钢筋以强度高、粘结强度好、延性可靠等优点广泛用于楼盖体系中。为了节省钢材用量，通常采用塑性设计。热轧钢筋的调幅值及相应的内力系数已有文献给出，但是冷轧扭钢筋却缺少这方面数据。给出的当调幅值为１５％时的冷轧扭钢筋混凝土连续梁、板的内力系数，为工程设计提供了可靠而实用的数据。

PLASTIC ADJUSTMENT DESIGN OF COLD-ROLLED AND TWISTED BAR REINFORCED CONCRETE CONTINUOUS BEAMS AND SLABS

The cold rolled and twisted bars,which have many advantages such as high strength,superior bondability and reliable ductility,are widely used in floor framing system In order to save steel consumption,the plastic adjustment design method is usually applied The internal force coefficients of hot rolled steel bars for corresponding plastic adjustment coefficients can be found in some reference but there are not any reliable data for the cold rolled and twisted bars as yet The internal force coefficients of cold rolled and twisted bar reinforced concrete continuous beams and slabs are given in this paper for plastic adjustment coefficient 15%,thus providing reliable and practical data for engineering design
