Available solutions for each of the key functions.

Key functions	⁢Solutions
Piping equipment penetration	Install reinforcing device at penetration; Solution A		Penetrate without reinforcing; Solution B
Transportation of modules	Limiting module height less than 3.3 m
Welding end-plate	Limiting flange width less than 120 mm
Connecting beam and column	Ensuring bolting space at end-plate
Connecting beam and slab	Integrate beam and slab support; Solution a		Separate beam and slab support; Solution b
Connecting beam and ceiling track	Connect track to web of beam with screw
Connecting beam and wall track	Ensuring flange width of 60 mm
Flexural strength of beam	Use hollow flange (flange thickness = web thickness); Solution I	Use hollow flange (flange thickness > web thickness); Solution II	Use open flange (flange thickness = web thickness); Solution III	Use open flange (flange thickness > web thickness); Solution IV
Minimize deflection and vibration of beam
Earthquake and wind resistance
