Question:
The figure shows a timber panorama terrace. Each internal plank has a width of b and a length of t. The characteristic self-weight is g0p,k (on unit area) for floor planking, g0b,k (on unit length) for the beams and g0h,k (on unit length) for the handrail! The characteristic imposed load on the terrace is qp,k (on unit area). The horizontal load on handrail is neglected (in this task).
a) Draw the structural model of an internal plank together with its characteristic total load, pp,k (on unit length)!
b) Calculate the characteristic reaction forces, Ap,k of the internal planks from the above (characteristic) values of loads! Give a sketch on the free body diagram of an internal plank!
c) Calculate the maximum (characteristic) bending moment, Mp,k of an internal plank!
d) Determine the characteristic loads, gb,k, qb,k and Gb,k on an internal beam! Draw the structural model of an internal beam together with its acting loads (gb,k, qb,k and Gb,k)!
