Question 1.3 (20 Points): Given a concrete floor of frame structure having a size of 27 m× 27 m with the column grid of 9 m×9 m in both longitudinal and transvers directions. Considering the floor system, two different plan arrangements have been proposed as shown in Fig. 1(a) and (b), respectively. The density load of floor layer is 5.0kN/m2, live load on floor is 4.0kN/m2 and the density load of beam is 4.5kN/m (Note: all are design values). (1) Please identify the difference of two plan arrangements and the corresponding influence on calculation of concrete slabs? (NOTE: when the length/width ratio >2, the concrete slab is simply regarded as one-way slab.) Fig. 1 Plan arrangements of floor system for Question 1.3
