and the resistance coefficient calculation formula were derived in which the effect of creep was considered. To study the characteristics of surrounding rock strength of red sandstone in tunnel lining design... that the resistance coefficient of surrounding rock reduces after considering the creep effect of red sandstone. When there appears weak surrounding rock crushing in the red sandstone and with plastic flow......

450×10-6. Creep deflection of self-compacting reinforced concrete beam decreases as the tensile reinforcing ratio increases. The deflection creep coefficient of self-compacting reinforced concrete beam after one and a half year is about 1.6, which is very close to that of normal reinforced concrete beams cast with vibration. Extra cautions considering shrinkage and creep behavior are not needed......
