Ten types of single shear screwed joints and nailed joints with different diameters, lengths, and side members were subjected to the monotonic and reversed cyclic loading. Test results were compared with the yield capacity and load-carrying capacity calculated by Yield Theory using the embedding test results of main and side members and the bending tests results of nails and screws. The calculated yield capacity and load-carrying capacity by Yield Theory showed good agreement with the experimental results. It was proved that Yield Theory is applicable to determining the allowable strength of screwed joints.
