Title of the articleThree-pin frame with reinforcing steel member
Abstract.This paper describes finite element model studies (FEM) of a new three-pin LVL frame with semi rigid eaves joint. There are many timber frames from engineered wood which have dowel cornice joint. For instance there is a conventional joint where its bridle type of connection between girder and column and dowels installed in circle pattern provide its rigidity and make it able to transfer flexural forces from girder to the column. The disadvantage of this type of joint is that because of its bridle type connection a cross-section of the girder and column in the cornice joint area are reduced at 30 and 60 %. The joint offered by constructive research department of the LTD «Transigcom» includes several findings. First is a curved bridle joint, and the second is a reinforcing steel member in the column. Curved bridle joint provides best transfer of the compressive forces and reinforce member provides transfer of the tensile forces from girder to column in the eaves node of frame. Accordingly FEM studies there are several peculiarities in the offered type of frame. These are: dependence between stress values in the cornice joint (amount of bending moment in the node) and pretension value in the reinforcing member of the column; classification of that type of joint as a semi-rigid.
Keywords.LVL, three-pin frame, bridle type joint.
