Research on Interaction Mechanism Between Frame Grids and Filling Blocks of Multi-ribbed Composite Wall
Five fundamental frame structures are tested under monotonic load in order to study the interaction mechanism between frame grids and filling blocks of multi-ribbed composite wall,and the failure process and failure characteristics are summarized in details.The experiments show that effect of the filling block is equivalent to that of hinged-diagonal strut.The calculation of width of the strut is given based on elastic foundation beam theory as well as the formulas of rigidity and intensity.Calculation shows that the simplified model can simulate mechanical properties of the fundamental frame structure in elastic stage,which offers a theoretical basis for analysis and design the multi-ribbed composite wall.
Abstract Although they create considerable economic benefits, industrial parks emit tremendous amounts of pollution and consume significant environmental resources. This investigation examines problems associated with managing an industrial park. It begins by defining an industrial park system and its sustainability. Next, using systems thinking, managing for results, driving-force-pressure-state-impact-response, and system dynamics, we develop a management framework and an indicator system. A framework with triple decision layers is established to link the management of an industrial park with its manufactories. Based on this framework, proposed indicators and their driving force–pressure–state–impact–response relationships are integrated into an optimization model to maximize sustainability, so that sustainability of an industrial park is assessed as total quantity management is performed. A prototype of a total quantity and sustainability management strategy for industrial parks is developed, based on ...
