What type of project does BIM particularly help with, as demonstrated by the Shanghai Tower?

What is one of the main benefits of BIM?

Which of the following is a major benefit of better visualization in BIM?

At which level of BIM maturity does 3D modeling first get integrated with 2D drawings?

Consider the simply supported beam shown below.     a) The pin support at A has a 10 kN vertical reaction force. What is the magnitude of the shear force at A?   b) what is the magnitude of the shear force at the application point of the 20 kN load?   c) what is the magnitude of the shear force 2 meters to the right of A?

Consider a simply supported beam subjected to a concentrated load, as shown below.  The beam has two vertical reactions. There is a reaction force at A and there is one at B. Is it true that these reaction forces are equal in magnitude?  

The beam shown below consists of 4 segments labeled AB, BC, CD, and DE.     a) What is the magnitude of the shear force in segment AB?   c) What is the magnitude of the shear force in segment BC?   b) What is the magnitude of the shear force in segment CD?   d) What is the magnitude of the shear force in segment DE?

Consider the following beam and its shear diagram.     The shear force becomes zero in the left segment of the beam, as marked on the diagram above. Where is the location of zero shear? Specify the distance from the left end of the beam to that location.
