Number of pages 02 Duration 70 minutes. Open-book. ANSWERS Question 1 4 10pts a. Arrange column layout - For the present building steel column bay shouldn t smaller than 5m and it should be modularised. - Columns should be arranged in the boundaries of the building including in the gable. b. Arrange roof purlin and girt - For cold-rolled purlin and girt to support the profiled sheeting and insulation its bay should be smaller and modularised. c. Arrange bracing system for roof and column plans - Bracing system for roof and column elevation should be arranged at the gables and along the building to support the wind load - Distance between two bracing systems should be smaller than 30m d. Verify cross-section of the girt . The following information should be presented - Choose structure diagram - Calculate loads on the girt dead load and wind load - Verify cross-section of the girt with respect to the stress and deflection. Question 2 5 10pts a. Dead load Dead load applied on the frame is composed of - cladding with sheeting and insulation - purlin and girt - bracing system. These static loads should be transformed into uniformly distributed ones and then linearly distributed and demonstrated on the transverse frame. b. Roof live load Standard roof live load is 30 daN m2. It will be uniformly distributed on the transverse frame. c. Crane load The following steps should be presented - draw influence lines for computation of crane pressures on the bracket beam - arrange vertical and horizontal pressures at wheel on the influence lines by supposing that the building have two crane bridges. - calculate vertical and horizontal pressures on the bracket beams and .
