Building system for skyscrapers

Abstract

A building system for skyscrapers includes a plurality of first building stories, a second building story located above the first building stories, and a plurality of third building stories located above the second building story. The second building story has a plurality of horizontal steel beams, a plurality of first vertical steel columns and a plurality of second vertical steel columns. The first vertical steel columns are located at a remote end of a lateral side of the building system, while the second vertical steel columns are located at a near end thereof. The fire resistance of the first vertical steel columns is superior to that of the second vertical steel column. Thus, while the building system is in a fire, the second vertical steel column would be affected more by the fire to reduce the vertical support thereupon than the first vertical steel column does.

What is claimed is: 
     
         1 . A building system for skyscrapers, having a lateral side, comprising:
 a plurality of first building stories, each of the plurality of first building stories having individually a plurality of horizontal steel beams and a plurality of vertical steel columns;   a second building story, located above the plurality of first building stories, having a plurality of horizontal steel beams, a plurality of first vertical steel columns and a plurality of second vertical steel columns, the plurality of first vertical steel columns being located at a remote end of the lateral side, the plurality of second vertical steel columns being located at a near end of the lateral side, a fire resistance of each of the plurality of first vertical steel columns being superior to that of each of the plurality of second vertical steel columns; and   a plurality of third building stories, located above the second building story, each of the plurality of third building stories having individually a plurality of horizontal steel beams and a plurality of vertical steel columns;   wherein, for the fire resistance of each of the plurality of first vertical steel columns is superior to that of each of the plurality of second vertical steel columns, thus in the case of a fire in the building system, vertical support strength of the plurality of second vertical steel columns is reduced more by the fire by compared to that of the plurality first vertical steel columns, so as to make vertical support strength of the second building story at the near end of the lateral side less than that thereof at the remote end of the lateral side.   
     
     
         2 . The building system for skyscrapers of  claim 1 , wherein each of the plurality of first vertical steel columns is coated by a layer of an inorganic nonmetallic material. 
     
     
         3 . The building system for skyscrapers of  claim 2 , wherein the inorganic nonmetallic material is one of concrete, asbestos and ceramics. 
     
     
         4 . The building system for skyscrapers of  claim 2 , wherein the inorganic nonmetallic material has a fire resistance up to 1,500° C. 
     
     
         5 . The building system for skyscrapers of  claim 1 , wherein the plurality of vertical steel columns of each of the plurality of first building stories, the plurality of first and second vertical steel columns of the second building story, and the plurality of vertical steel columns of each of the plurality of third building stories are arranged in a predetermined correlated pattern so that the corresponding vertical steel columns at the neighboring stories are axially engaged so as beneficially to construction and strength of the building system. 
     
     
         6 . The building system for skyscrapers of  claim 5 , wherein any of the vertical steel columns of any of the building stories has an upper surface including an engagement groove and a lower surface including an engagement protrusion, the protrusion of one said vertical steel column being to plug into the engagement groove of another said vertical steel column located under the one said vertical steel column. 
     
     
         7 . The building system for skyscrapers of  claim 6 , wherein a layer of an inorganic nonmetallic material is included to be located between the engagement groove and the engagement protrusion. 
     
     
         8 . The building system for skyscrapers of  claim 7 , wherein every two of the neighboring building stories are separated by a floor.
