Integral stiffened plate ultimate load calculation method

The invention provides an integral stiffened plate limit load calculation method. The method comprises the steps that an integral stiffened plate is separated into a skin part and a rib part; calculating the strength value of the rib according to a calculation method of the pressure loss strength; calculating the strength value of the skin; and calculating the limit load of the whole stiffened plate according to the strength value of the rib and the strength value of the skin. 本申请提供一种整体加筋板极限载荷计算方法，方法包括：将整体加筋板分离成蒙皮部分和筋条部分；根据压损强度的计算方法，计算筋条的强度值；计算蒙皮的强度值；根据筋条的强度值和蒙皮的强度值，计算整体加筋板极限载荷。
