In view of China’s development trend of green building and building industrialization, based on the emerging requirements of the structural engineering community, the development and proposition of novel resource-saving high-performance steel-concrete composite structural systems with adequate safety and durability has become a kernel development trend in structural engineering. This paper provides a state of the art review of China’s cutting-edge research and technologies in steel-concrete composite structures in recent years, including the building engineering, the bridge engineering and the special engineering. This paper summarizes the technical principles and applications of the long-span bi-directional composite structures, the long-span composite transfer structures, the comprehensive crack control technique based on uplift-restricted and slip-permitted (URSP) connectors, the steel plate concrete composite (SPCC) strengthen technique, and the innovative composite joints. By improving and revising traditional structure types, the comprehensive superiority of steel-concrete composite structures is well elicited. The research results also indicate that the high-performance steel-concrete composite structures have a promising popularizing prospect in the future.

为了研究楼板在复合梁的格栅中的弯曲性能以及面内效应,我们对一种全尺寸复合楼板进行了试验,以降低混凝土板沿主梁线纵向开裂的趋势。在钢板定向平行于梁却不并排放置的情况下,这样的改变非常重要。在这种情况下,重要的是证明从剪切连接件中传递的局部力,以及与欧洲规范4 相比,其所需的横向钢筋量有所减少。研究机制涉及混凝土板产生的面内压缩力,这是由于楼板受到外围的复合梁支撑产生了约束作用;而次梁作为横向纽带用于抵抗楼板中的作用力,否则会导致混凝土板沿主梁线分裂。我们对主梁中心线及外围梁的开裂趋势进行了精密测试,这是自20世纪90年代初卡丁顿试验以来,在实验室条件下进行的第一次大型楼板试验,虽说卡丁顿试验并没有失败。这次楼板试验的目的是即使主梁传递的纵向力相对较高(即设计为全剪切连接件),但混凝土面层中钢筋最小配筋率仅为0.2%。该试验证实,尽管在钢板不连续,以及使用欧洲规范4中规定的横向分布钢筋最小配筋率的情况下,主梁仍然达到了其塑性抗弯性能。在此基础上,我们提出了无 U 形钢筋(U-bars)的边梁剪切连接件的折减系数。

Without modifying the cam contour, a cam mechanism with a variable input speed trajectory offers an alternative solution to flexibly achieve kinematic and dynamic characteristics, and then decrease the follower’s residual vibration. Firstly, the speed trajectory of cam is derived by employing Bezier curve, and motion continuity conditions are investigated. Then the motion characteristics between the plate cam and its roller follower are derived. To analyze the residual vibration, a single degree of freedom dynamic model of the elastic cam-follower system is introduced. Based on the motion equation derived from the dynamic model, the residual vibration of the follower is yielded. The design procedure to improve the kinematic and dynamic motion characteristics is presented and two design examples with discussions are provided. Finally, the simulations of the kinematic and dynamic models by ADAMS are carried out and verified that the design models as well as the performances of the mechanism are feasible.

Exact solutions for the flexural vibrations of circular plates having elastic edge conditions along with rigid concentric ring support have been presented in this paper. Values of frequency parameter for the considered circular plate are computed for different sets of values of elastic rotational and translation restraints and the radius of internal rigid ring support. The results for the first three modes of plate vibrations are computed and are presented in tabular form. The effects of rotational and linear restraints and the radius of the rigid ring support on the vibration behavior of circular plates are studied over a wide range of non-dimensional parametric values. The values of the exact frequency parameter presented in this paper for varying values of restraint parameters and the radius of the rigid ring support can better serve in design and as benchmark solutions to validate the numerical methods obtained by using other methods of solution.
