文摘:分析讨论了目前国内外在深冲用薄板生产中的成分控制、热轧、卷曲工艺、铁素体区轧制、 trip钢生产、冷轧与退火工艺以及钢板表面质量控制方面的新进展和趋势 - By calculating large quantity of examples , this text studies earthquake resistant behavior of tapered portal frame with pined bases and analyzes its natural frequency , natural period of vibration and vibration mode . by comparing interior forces of pillar top , beam end and span midpoint in two conditions that seismic action effect participates combination of forces and not when portal frame is n ' t changed , ensure conditions that combination of seismic action effect has controlling f unction during tapered portal frame design , and tapered portal frame demands anti - earthquake design
本文通过大量算例分析，研究柱脚铰接楔形变截面门式刚架的抗震性能，并对其自振频率、振型进行了分析；通过比较地震作用效应参与荷载组合与不参与荷载组合两种情况下，梁柱截面尺寸不变时，柱上端、梁端、跨中截面处的内力大小，确定在什么情况下地震作用效应组合起控制作用，变截面门式刚架需要进行抗震设计。
