MS 544 : PART 11 :SECTION 3 : 2001 (CONFIRMED:2020)
CODE OF PRACTICE FOR STRUCTURAL USE OF TIMBER : PART 11 : RECOMMENDED SPAN TABLES AND THEIR CALCULATIONS : SECTION 3 : CEILING BINDERS
This Section of MS 544 : Part 11 recommends a calculation basis for the permissible clear span of ceiling binders used in traditional pitched roof construction, i.e. not including trussed roofs. The method of calculation is for single span ceiling binders formed from solid timber and supported at each end by external or internal walls. The space above the ceiling binders is assumed to be accessible, thus both uniform loads and a single concentrated load are considered. A typical example of roof construction is given in Figure 1. This Section of MS 544 : Part 11 is applicable to the species, strength groups and grades of timber given in MS 544 : Part 2
