In this paper the results of investigation of live load on floor in the 12 office buildings of reinforced concrete construction or steel-reinforced composite construction is expressed. Buildings investigated were the newly built buildings completed after 1955. The object of investigation was divided into two. One is for main office space and the other for subordinate office space (parlour, meeting room, directors' room, stack room, computer room, etc.). The matters for investigation were as follows : (1) Ratio of floor area occupied by articles (furniture, desk, chair, papers and file cabinet, book and book cabinet, locker, miscellaneous articles for business) to total floor area of a room. (2) Mean value of total weight of articles per unit floor area. (3) Mean value of total weight of articles divided by the floor area occupied by articles. (4) Load by human crowd per unit floor area. (5) Live load (weight of articles plus load by human crowd) (6) The value of (2)/(5) (7) Mean value of floor area divided by the number of office workers of a room. The office buildings recently built are different from old buildings in the points of function of office, structural design and others. Therefore, the value of design live load on floor should be reexamined by new date. The authors believe that the results expressed here will be available for the above aim as basic data.
