模拟实验

Based on the model calculation,an FAPP ventilation system was madein Beijing Poultry Breeding Company.Through running test and a series ofphysical and chemical characteristic measurement,the distribution of flowspeed in length,and breadth was given.The average temperatureand rel-ative humidity,the amplitude of T and RH per day of 30 days in winter,and instantaneous T and RH in 24 hours wre measured in FAPP house,com-paring house and outside,the result shew that FAPP ventilation system wassuperior to comparing house.The dust concentration and microrganism con-tent were also measured in the rearing piriod of poultry,the value in FAPPhouse was junior to comparing house.

In this thesis, an effective analysis model, named "equivalent column" model, was proposed for the wall inside the RC frames, and consideration the wall can resist axis force, moment, and shear force. The "equivalent column" model can simulate the brick wall, the RC wall as well as the wing wall. The experimental and analytical results of the RC column, pure RC frame, RC frame in-filled with RC wall, RC frame in-filled with brick wall, RC frame in-filled with wing wall, and RC column repaired by using the steel wire cables and the carbon fiber reinforced plastics were compared in the thesis.
