| Abstract: | It has been established the load effect under the action of diversified combination of loads and series-parallel connection unit of Regarding failure unit as to collapse mode by analyzing strength and loads of the Derrick structure,and the calculational model of Structural Reliability of the Derrick has been constituted with these series-parallel connection units.At the same time,the calculational method of the its reliability has been given and the calculational formula calculated by first-order second-moment method has been deduced. |
