Based on three kinds of construction processes,which are often applied in the mega-frame of tall building,three analytical methods of the vertical load effects,which taken into account the construction process effects,are introduced,and the corresponding computational procedure is presented.

Vehicle load effects were calculated and compared with that of current bridge design codes.

Study on effects of simulated space radiation environment on optical materials;

The effect of the active powders relied on UPFA(ultrapulverized fly ash) on the flowability and strength of cement mortar and the slump and strength of concrete was investigated systematicly under the condition of the low waterbinder ratio and high flowability.

This paper discussed the effect of some factors on characteristic value of soil and water loss,which has been completed by simulating rainfall experiment in the south region of the Loess Plateau.
