It puts forward a calculation method for predicting failure load using “Grey System”theory and suggests to use this method in model experiment for pressure hull of the active submarine in the future.
并提出用“灰色系统”理论预测破坏载荷的计算方法，建议今后模型实验和现役潜艇的耐压船体寿命估算中可采用这种方
The failure loads that relatively coincide with experimental values in most cases are obtained based on the energy principle in fracture mechanics.
借鉴复合材料力学的分析方法,建立一种分层剪滞模型,并结合线弹性断裂力学的能量法,研究了碳纤维薄板加固含裂缝素混凝土梁和钢筋增强混凝土梁的四点弯曲破坏问题,求得的破坏荷载与试验较吻合。
The purpose of this reserch is to study the effects on joints failure load by stirrups in joint region,concrete strength grade,reinforcements ratio of beams and columns and stirrups of beams and columns.
通过对13个L形和T形柱节点进行非线性有限元分析,研究了在单调荷载作用下,节点核心区箍筋、混凝土强度等级、梁柱纵筋配筋率、梁柱配箍率对L形、T形节点破坏荷载的影响。
