The workshop concerned is a portal frame structure with four spans and two slope roofs, of which ten columns need cutting for expanding span. The design and reconstruction project of column-cut supported by joist were introduced, which includes column reinforcement, connection rebuilding between brackets and crane beams, and the changing of rigid joint into hinge joint. The construction scheme was put forward in the light of the characteristics of the reinforcement and reconstruction. Spot test of dynamic performance on the workshop and comparison with theoretical analysis results show that the column-cut supported by joist design is effective and the reconstruction project is successful.展开更多

Based on the economic attributes of public goods and personal belongings, this paper divides the old-age service into the old-age service of private property and the properties of public goods （pure public goods and quasi-public goods） according to the family status, economic status and health status of the clients. This paper explores the theoretical basis of price decision mechanism and effective supply of these two kinds of old-age services, and finally puts forward the concrete measures of the reform of the old-age service price in the light of the actual situation of the current pension service in our country.展开更多
