新型不锈钢管固废混凝土构件受弯性能研究

open access: yesJianzhu Gangjiegou Jinzhan
进行了6个不锈钢管混凝土试件的纯弯试验研究,分析了在弯曲荷载作用下,混凝土类型和截面形状对新型S35657奥氏体不锈钢管混凝土构件的破坏模态、荷载-变形关系、抗弯刚度与承载力的影响规律。试验结果表明:固废混凝土对新型不锈钢管混凝土纯弯构件的整体破坏模态影响不大,但固废混凝土有利于提高构件的抗弯承载力与刚度。随后建立了不锈钢管固废混凝土纯弯构件有限元模型并验证了既有材料模型的适用性,最后分析了各规范抗弯承载力计算方法的适用性和预测精度。

循环周转型临时看台支承架体重复对比试验研究

open access: yesJianzhu Gangjiegou Jinzhan
北京冬奥会为积极响应国家走绿色可持续发展道路,采用了大量支承架体用于临时看台或舞台的搭建。为研究赛后的临时看台支承架体能否安全合理地再次使用,本文以索氏不锈钢插销式节点临时看台支承架体为研究对象,设计并制作了一个2×2足尺模型,共进行了两次试验,即在首次水平加载试验结束后,将该试验架体搭建在室外经历长时间严寒风雪环境条件后再重复做一次试验,重点对比分析了其在4种不同恒载与水平荷载组合作用下的整体结构变形模式、力学性能及典型位置峰值应变等。研究结果表明:在恒载为0 kN⋅m-2、0.5 kN⋅m-2、2 ...

The Industrial Application of Plate Heat Exchanger and Root Cause Failure Analysis [PDF]

open access: yes, 2012
换热器是国民经济和工业生产领域中应用十分广泛的热量交换设备,换热器作为一种利用能源与节约能源的有效设备,它的性能对产品质量、能量利用率以及系统运行的经济性和可靠性起着重要的作用,有时甚至是决定性的作用。 而传统的立置管壳式换热器的传热效率较低,所需传热面积大,实际投用常常采用并联方式。但是多台并联对物流的均匀分配带来困难,而且存在设备空间大,耗材多的缺点。新型焊接板式换热器作为高效换热器,具有换热效率高、顶部温差小、压降低、占地小和费用低的诸多优点,适合其在炼油、化工领域的广泛使用 ...
