利用竹材用于永久性建筑,既有积极的经济价值,又可缓和木材供应紧张。 (一)竹木组合梢钉计算: 由于钉受弯曲,孔壁受挤压,在松枞等木结构中,梢钉每一剪力面之容许力,沿用以下三式中之最小值: [T_H]_u=300d~2 由于梢钉的弯曲 [T_H]_c=40cd 由于中部木料挤压
The use of bamboo for permanent construction has both positive economic value and eased timber supply. (a) Bamboo and wood composite pin calculation: Due to the bending of the nail, the hole wall is squeezed. In the wooden structure such as the pine bark, the allowable force of each shear face of the pin nail follows the minimum value of the following three formulas: T_H]_u=300d~2 Due to the bending of the tip [T_H]_c=40cd due to the central wood extrusion
