The authors discuss the factors influencing the design and choice of materials used in the construction of multi-storey car parks. Recommendations are given for the positioning of signs and columns to cause minimum obstruction and inconvenience. Minimum stall widths for unobstructed parking are suggested; clear markings are essential for full use of the static capacity. Floors should be watertight to prevent seepage; perimeter barriers should be capable of providing an effective resistance to a moving car which could be accelerating in bottom gear. Reasons for discarding designs using an uncased steel-formed structure with compositely designed pre-cast concrete floors are given. Cast in-situ concrete has been chosen for the frame and floors based on a two-pinned portal frame structure, constructed in a nominal module of 4.8 M. Floors have reinforcements to control shrinkage and cracking besides the main reinforcement in their ribs. Two types of frame are illustrated, system 1 with external columns and system 2 with inset tapered columns; the relative merits of each type are discussed. /TRRL/
