受拉、剪的高强螺栓连接计算方法的研讨

On the Bolting Calculation Method of Hightension Bolt Subjected to Tension-Shear

受拉、剪的高强螺栓的连接计算方法在现有的钢结构理论中，高强螺检容许承载力按［ＮＬ］＝０．７ｎｍ＋（Ｐ－βＴ）计，笔者对该公式中、高强螺栓所受外拉力Ｔ值提出了新计算方法，并论证了采用钢结构的安全系数Ｋ代替原理论中试验值β的合理性.

The author has adopted a different calculation method or T value from those accociated with the conventional analysis of steel structure design formula[(NL] = 0.7 nmf (P-βT)) that is, a new idea for calculation of the hightension bolt subjected to tension-shear.Here, the feasibility that the coefficient K of steel structure safety substitutes the test value βis discussed and proved.
