螺栓群在弯矩和轴拉力共同作用下的螺栓数设计

DESUGN OF BOLTS OF THE BOLTED CONNECTIONS SUBJECTED TO COMBINED BENDING MOMENT AND AXIAL TENSION

提出了螺栓群（包括普通螺栓和高强度螺栓）在弯矩和轴心拉力共同作用下的螺栓数设计公式和方法．算例表明，设计公式简单实用，计算方便，可避免反复试算．

This paper proposed formulae of design of bolts (ordinary bolts and high-strength bolts) which are subjected to combined bending moment and axial tension. Examples show these formulae are very simple and satisfactory results may be obtained without repeating trial calculation.
