Building system provided with a crash lateral side that is adapted to collapse firstly under high-heat temperature

Abstract

A building system is provided with a crash lateral side that is adapted to crash firstly under high-heat temperature. The building system includes a first building structure having a plurality of first horizontal beams and a plurality of first vertical support structures; a first fire-resistant floor erected uprightly on the first building structure; and a second building structure erected uprightly on the first fire-resistant floor, and having a plurality of second horizontal beams and a plurality of second vertical support structures. The second vertical support structures adjacent to the crash lateral side have a relatively low fire-resistant strength when compared to remaining portions of the second vertical support structures away from the crash lateral side such that the second vertical support structures adjacent to the crash lateral side are adapted to collapse toward the crash lateral side under the high-heat temperature.

1 . A building system provided with a collapse lateral side that is adapted to collapse firstly under a fire, comprising:
 a first building structure including a plurality of first horizontal beams and a plurality of first vertical support structures;   a first fire-resistant floor erected on a top end of said first building structure; and   a second building structure erected uprightly on said first fire-resistant floor, and including a plurality of second horizontal beams and a plurality of second vertical support structures;   said second vertical support structures adjacent to the collapse lateral side have a relatively low fire-resistant strength compared to remaining portions of said second vertical support structures away from the collapse lateral side such that said second vertical support structures are adapted to first collapse toward the collapse lateral side under the fire;   each of said first vertical support structures has an upper surface that is used for engaging with said first fire-resistant floor and that is formed with a plurality retention recesses, each of said second vertical support structures has a bottom surface that is to be disposed on said first fire-resistant floor and that is formed with a plurality of downward protrusions extending respectively into said plurality retention recesses, the building system further comprising a third heat-resistant material filling a gap between said retention recesses and said downward protrusions in order to isolate heat conduction thereamong;   each of said first and second vertical support structures is a steel structure and is constituted by at least one column or wall; and   each of said first and second building structures have a plurality of stories.   
     
     
         2 . (canceled) 
     
     
         3 . The building system according to  claim 1 , wherein said second vertical support structures adjacent to the collapse lateral side are coated by a first heat-resistant material having a relatively low fire-resistant strength while said remaining portions of said second vertical support structures are coated by a second heat-resistant material having a relatively high fire-resistant strength. 
     
     
         4 . (canceled) 
     
     
         5 . (canceled) 
     
     
         6 . The building system according to  claim 1 , further comprising:
 a second fire-resistant floor erected on a top end of said second building structure; and   a third building structure erected uprightly on said second fire-resistant floor, and including a plurality of third horizontal beams and a plurality of third vertical support structures;   wherein, said third vertical support structures adjacent to the collapse lateral side have a relatively low fire-resistant strength compared to said remaining portions of said second vertical support structures away from the collapse lateral side such that said third vertical support structures is adapted to collapse toward the collapse lateral side under the fire.   
     
     
         7 . The building system according to  claim 6 , wherein the vertical support structures of the second building structure have a relatively stronger vertical support strength when compared to the vertical support structures of the third building structure so that under the fire, said third vertical support structure collapses first toward the collapse lateral side when compared to said second vertical support structure. 
     
     
         8 . The building system according to  claim 7 , wherein the quantity of said third vertical support structures with said relatively low fire-resistant strength in said third building structure is greater than the quantity of said second vertical support structures with said relatively low fire-resistant strength in said second building structure.
