We studied seven common branches collected at early winter in Beijing. We performed three point bending test for the branches when they were fresh or air-dried after six months,respectively. We calculated the bending modulus of elasticity( MOE),modulus of rupture( MOR) and strain of these branches,and tested the water content,basic density and airdried density of the fresh and dry branches after the bending tests. MOE of the fresh branches were in 1 368- 4 327 MPa,while those of the dry ones were in 2 827- ...
