A multidirectional force measuring ball type steel support can precisely measure and transmit horizontal loads, in the vertical direction and other directions, of the support and can meet the requirements for normal displacement and rotation of beam bodies. The multidirectional force measuring ball type steel support comprises an upper support plate, a spherical cap liner plate, a piston and a lower anchor plate. An annular boss extending downwards is arranged at the bottom of the upper support plate. A force measuring ring is arranged between the annular boss and the annular outer side wall of the piston. Radial force measuring sensors are arranged on the force measuring ring at intervals in the radial direction. An installation cavity is formed between the piston and the lower anchor plate. A force measuring elastic body is arranged in the installation cavity, wherein the top face and the bottom of the force measuring elastic body make contact with the piston and the lower anchor plate respectively. Vertical force measuring sensors are arranged on the force measuring elastic body at intervals in the radial direction.
