This paper presents conditions to prevent global buckling of pin-ended tube-in-tube buckling restrained braces. When one end of the restraining member is rigidly connected to the pin joint and the ...sliding joint is adopted at the other end, the deflection of the brace makes an asymmetric curve and the local deformation of the restraining member may occur at the sliding joint. The method to calculate deflection of the core member and bending moment of the buckling restraining member is led theoretically. Validity of proposed methods and conditions to prevent global buckling are verified through parametric study on cyclic loading tests and FEM analysis.

This paper discusses the development process and the function of environmental partnership organizations that act in relation to various stakeholders in a region, based on the case study of “Miyako ...Agenda 21 Forum” in Kyoto City. Agenda 21 Forum was established in 1998. Environmental partnership organizations were active in working to prevent global warming, but their activity has been stagnant since 2005. Agenda 21 Forum has functioned as a platform, round-table, and intermediary that promotes partnership-based activities in Kyoto City. However, after the original goal was achieved to a certain level, organizations did not reset their goals, despite changes in community attitudes to global warming prevention, and their significance to the local stakeholders declined. This is the reason for their stagnation, New roles and goals are needed as an environmental partnership organization, associated with corresponding organizational change.
