This paper introduced the reconstruction practice and detailing of a high-rise reinforced concrete frame-shear wall structure. To fully utilize the old structure and meet the requirement of the reconstructed structure, certain measures have been put forward. The enlarging of concrete pile cap and adding strip foundation-beam were used to support the new added shear wall. The reconstruction concept detailing of the roof of basement, the enlarging of the beam or column sections and the application of the inclined column are introduced. The whole structure analysis shows that the reconstructed structure is safe enough to meet all the requirement of the designing code and the settlement observation shows that the deformation of the whole structure in gravity is small. The paper shows the design and detailing of the reconstructed engineering is effective and will be valuable to the similar engineering structures.

Contraposed the hydration heat of large volume concrete, based on the introduces of raw material, the effect of fly ash mix amount in large volume pile cap concrete was mainly analyzed combined with project case of Yellow River Bridge in Baotou-Shulinzhao Highway. Moreover the temperature and temperature stress in different mix amounts were analyzed by the finite element software to confirm the appropriate mix amount of fly ash and the mix proportion of concrete. Finally, the consequence of the large volume pile cap temperature control was certified by the practice of construction.
