Through heating, raising moisture content and improving the surface conditionof bamboo, plasticity of bamboo can be increased, bending stress can be reduced to opposite direction.
竹材通过加热、提高含水率和改善竹材的表面状态等三种途径来增加其塑性、减小展平时的反向弯曲应力。

The yield and tensile strength of the welded joints of the two kinds of materials increase under dynamic loading and prestrain condition that have little effect on the plasticityof structural steel.
