LIMIT VALUE OF AXIAL COMPRESSION RATIO OF SRC COLUMN WITH H-SHAPED OR CROSS STEEL SECTION
-
摘要: 给出了钢骨混凝土柱界限破坏时,最外侧受拉钢筋先屈服的条件;研究了配置工字形钢骨时,绕强轴受弯和绕弱轴受弯的轴压比限值公式,并在此基础上提出了配置十字形钢骨的轴压比限值计算公式。Abstract: The paper gives out the condition of yielding first for the tension steel bar in the balanced failure of SRC column. The limit value formulae of axial compression ratio for SRC column are derived including to bend around strong axis and weak axis of H- shaped steel section. Based on these formulae, the paper puts forward the limit value formula of ax ial compression ratio of the cross steel section.
