Simulation of a Person or Object Falling onto a Structure???

I’m interested in doing some type (TBD) of analysis to simulate the effects, as noted below.  I need some “Technical Advice” on how to setup and what type of analysis within Simulation-Premium can be used to evaluate the effect of a person or object falling on top of a structure from a given height, as defined at the start of this email message.

 

Please read from the beginning and give me some quick technical advice on this subject.

 

Thanks,

Personal fall arrest systems must:

a)         Be rigged so that if an employee falls, it is the shortest possible distance so as to minimize the impact and swing of the arrest. The absolute maximum free fall distance is six feet.

b)         Limit maximum arresting force on an employee to 1800 pounds with a body harness.

c)         Bring the employee to a complete stop and limit maximum deceleration distance to 3.5 feet.

d)         Have sufficient strength to withstand two times the potential impact energy of an employee free-falling a distance of six feet, or the free-fall distance permitted by the system, whichever is used.
