based on the structural determination of prestress pin joint assembly, the structural characteristics of the prestress pin joint structures are discussed in this paper.
预应力桿件体系的结构判定是预应力结构设计的基本问题,更是新型预应力桿件结构体系研究的重要基础理论。
the action arms suspend span above the batch roller and two pin joint points of action arms lie at two sides of axial center of the batch roller and contact to the end of lateral box and batch roller.
