Introduction

This wooden slab design of a single-storey industrial building has been developed in accordance with the design assignment and the current SNiP.

The initial design data is as follows:

1. Building length 51 m

2. Span of the building 15 m

3. Construction truss type - triangular

4. Climatic region 3

5. Group of designs under the terms of operation of A1

Frame Pitch Definition

Frame pitch is the distance between the axes of two adjacent frames. It depends on the loads on the coating and for a warm roof is usually from 3500 mm to 5000 mm. Distance from axes of extreme frames to axes of nearest frames is 0.8 of pitch value. Designed building - with internal heating, climatic area 3. The pitch of the frames is determined by the formula a = L/( n0.4). We take n = 13, then with the length of the building L = 51000 mm, pitch a = 4048, and the distance from the axes of the extreme frames to the axes of the nearest frames is 3238 mm.
