Wind analysis of bamboo based shed structure and design of base connection for bambcrete column

This paper is one of the four papers in series dealing with various aspects of bamboo related research in Structural Engineering carried out in India. Specifically, this paper presents a detailed wind load analysis of a typical bamboo shed structure, 6 x 6 m in size, in accordance with the Indian standard IS: 875 (Part 3)-1987. Wind is considered both along as well as normal to the ridge. The columns are modeled as rigidly fixed at the base and tied together by bamboo bow beam at top in normal to the ridge and by bamboo beams in the longitudinal direction. No rotational restraint is assumed at the top in any direction. Final axial loads, shears and bending moments at the column based resulting from the combination of dead loads and wind loads are computed and utilized in the conceptual design of suitable base connection. Two alternative designs are presented for the base connection.
