For the design engineers first proposed solution, determine the internal forces of all memebers of the most critical frame under the combination of permanent, imposed and wind load altogether.
For the reinforced concrete frame, calculate the bending moment at any chosen internal point.

Lifeboat Station Building The final design for a Lifeboat Station Building is sketched in the figure below. Level 1 houses a lifeboat and towing tractor and has an overhead crane over its length. From the pavement on the east side, a doorway at level 2 provides access to a lobby, changing rooms and a control room leading to a seafront balcony. A 10 m walkway provides access from the level 2 changing rooms to the lifeboat. The south elevation to the lifeboat station is provided with an 8.0 m high electrically operated roller shutter door. Imposed Loading Pitched roof, Services: 0.6 kN/m? • All floors: 5.0kN/m2 • Crane capacity required: 20KN A 1-hour minimum fire protection is required for all structural members. Structural Design: The design engineer proposed two distinct and viable solutions for the proposed structure: a) A number of reinforced concrete frames, each consisting of 2 spans, running from east to west., carrying the complete load. b) A steel structure that is formed from columns, supporting a number of beams, for the office side of the building together with a truss structure that carries the roof over the boat and the crane railings. The engineer estimates: a) The permanent load for the office is 2 kN/m2 b) The permanent load for the roof is 1 kN/m² c) A wind loading of 1 kN/m² acts from west to east. Required: a) For the first proposed solution, using StaadPro, determine the internal forces of all members of the most critical frame, under the combination of permanent, imposed and wind load together. (8 Marks) b) For the reinforced concrete frame, using the bending moment diagram from StaadPro, evaluate, by hand calculation, the bending moment at a chosen internal point. (4 Marks) c) For the second solution using StaadPro, determine the internal forces of all members of the truss that will be used to support the crane. (5 Marks) d) For the truss structure, using hand calculation, verify the internal force for one internal member. (3 Marks)

A report that contains: a) Sketches of the 2D frames that were analysed. Each sketch should clearly indicates the type of support used, the internal connection assumed and the loading applied. b) Diagrams that show the relevant internal forces. The diagrams should contain enough information to enable the designer to recompute any other required value. For the truss structure, a table listing the internal forces is more appropriate. c) The requested hand calculations that were carried out to validate the results.
