ssy

The results show that , in the condition of small scale yielding ( SSY ), the peak value of loadings linearly increases with decreasing pure Al sheet thickness .

结果表明：在小范围屈服条件下随着中间纯铝层厚度的降低，其峰值载荷呈线性增加；

The incremental launching method ( SSY ) is employed by the continuous prestressed box girder of the west bank approach bridge , with spans of 8 × 42m in light of the ground circumstance .

根据地形地貌的情况，西引桥8×42m预应力连续箱梁采用多点顶推法施工。
