针对通常的纵横弹性网格对汉字"撇、捺"笔画特征提取的不足，提出一种新的网格构造技术——对角弹性网格，它由45°和135°的对角直线构成，将汉字图像划分为多个菱形，能够很好地适应汉字在"撇、捺"方向的变化。

Study results indicate that the horizontal projection length of diagonal cracks cannot be predicted accurately when considering shear span ratio and strength ratio of longitudinal steels to stirrups separately. However the horizontal projection length can be well predicted through integrating these two influence factors due to their well representation of the entire process of diagonal cracks' occurring and development.
