影响蜂窝状钢骨混凝土L形柱性能的参数分析

针对钢骨混凝土L形柱,提出了一种新型的钢骨形式.为了掌握该构件的受力特性,通过ANSYS软件,对腹板开洞率、配钢率、加载角、偏心距等影响因素进行理论分析.结果表明,在相对偏心距较大的情况下构件承载力会急剧下降,而且存在不利荷载角的问题;腹板开洞能有效地减少钢骨与混凝土之间的滑移,但对承载力的削弱有限,并就该构件的最佳配钢率提出建议.

Analysis on the influence parameters of the honeycomb-shaped SRC L-section column on its performence

For the L-section column with steel reinforcement concrete, a new type of steel arrangement was proposed. Having mastered the stress characteristics of this kind of component, some useful conclusions for engineering design reference were suggested. We made the theoretical analysis on many influence factors by ANSYS software, such as hole ratio, steel ratio, loading angle, eccentricity and so on. It was discovered that under relative large eccentricity the component supporting capacity will drop sharply, also exists unfavorable loading angle problem, the web hole can reduce the slipping between steel and concrete effectively, but weakens the supporting capacity limitedly and the optimal steel ratio was proposed.
