be less than a uniformly distributed live load of 15 psf (0.74 kN/m 2 ). 1607.6 Truck and bus garages. Minimum live loads for garages having trucks or buses shall be as specified in Table 1607.6, but shall not be less than 50 psf (2.40 kN/m 2 ), unless other loads are specifically justified and approved by the build- ing official. Actual loads shall be used where they are greater than the loads specified in the table. TABLE 1607.6 UNIFORM AND CONCENTRATED LOADS LOADING CLASS a UNIFORM LOAD (pounds/linear foot of lane) CONCENTRATED LOAD (pounds) b For moment design For shear design H20-44 and HS20-44 640 18,000 26,000 H15-44 and HS15-44 480 13,500 19,500 For SI: 1 pound per linear foot = 0.01459 kN/m, 1 pound = 0.004448 kN, 1 ton = 8.90 kN. a. An H loading class designates a two-axle truck with a semitrailer. An HS loading class designates a tractor truck with a semitrailer. The numbers fol- lowing the letter classification indicate the gross weight in tons of the stan- dard truck and the year the loadings were instituted. b. See Section 1607.6.1 for the loading of multiple spans. 1607.6.1 Truck and bus garage live load application. The concentrated load and uniform load shall be uniformly dis- tributed over a 10-foot (3048 mm) width on a line normal to the centerline of the lane placed within a 12-foot-wide (3658 mm) lane. The loads shall be placed within their indi- vidual lanes so as to produce the maximum stress in each structural member. Single spans shall be designed for the uniform load in Table 1607.6 and one simultaneous concen- trated load positioned to produce the maximum effect. Mul- tiple spans shall be designed for the uniform load in Table 1607.6 on the spans and two simultaneous concentrated loads in two spans positioned to produce the maximum neg- ative moment effect. Multiple span design loads, for other effects, shall be the same as for single spans. 1607.7 Loads on handrails, guards, grab bars and vehicle barriers. Handrails, guards, grab bars as designed in ICC A117.1 and vehicle barriers shall be designed and constructed to the structural loading conditions set forth in this section. 1607.7.1 Handrails and guards. Handrail assemblies and guards shall be designed to resist a load of 50 plf (0.73 kN/m) applied in any direction at the top and to transfer this load through the supports to the structure. Glass handrail assembliesand guards shallalso comply with Section 2407. Exceptions: 1. For one- and two-family dwellings, only the single concentrated load required by Section 1607.7.1.1 shall be applied. 2. In Group I-3, F, H and S occupancies, for areas that are not accessible to the general public and that have an occupant load less than 50, the minimum load shall be 20 pounds per foot (0.29 kN/m). 1607.7.1.1 Concentrated load. Handrail assemblies and guards shall be able to resist a single concentrated load of 200 pounds (0.89 kN), applied in any direction at any point along the top, and have attachment devices and supporting structure to transfer this loading to appropri- ate structural elements of the building. This load need not be assumed to act concurrently with the loads specified in the preceding paragraph.
