新型波形钢-UHPC组合桥面板抗弯性能研究

Jianzhu Gangjiegou Jinzhan
文中提出了一种新型波形钢-超高性能混凝土（ultra-high performance concrete， UHPC）组合桥面板结构体系，围绕该类桥面板的抗弯性能开展深入研究，为进一步探究其疲劳性能奠定基础。首先，针对该组合桥面板结构设计制作了3个试件，并对其进行了3组正弯矩作用下的足尺模型试验，探究不同剪跨长度下结构的破坏模式、承载能力、钢-UHPC层间滑移等关键力学指标的发展规律。在此基础上，建立了考虑UHPC材料非线性和钢-UHPC层间接触非线性的有限元模型 ...

一种带轴向载荷控制的旋转弯曲疲劳实验的装置和方法

, 2015
本发明公开一种带轴向载荷控制的旋转弯曲疲劳实验的装置和方法，该装置包括旋转弯曲疲劳加载装置以及对试验样品施加轴向力的轴向载荷加载与控制装置。本发明以现有的旋转弯曲疲劳装置和方法为基础，通过增加轴向载荷加载与控制装置保证了样品在旋转弯曲疲劳加载的条件下，同时受到轴向载荷作用，从而实现不同应力比条件下的旋转弯曲疲劳试验。控制轴向载荷随时间周期变化，从而实现两种不同频率载荷作用下的复合疲劳。关闭旋转并去除弯曲载荷，控制轴向载荷单调增加，从而实现单调拉伸试验。本发明的带轴向载荷控制的旋转弯曲疲劳实验装置结构简单、

家兔胫骨的三点弯测试

, 2008
目的:探讨采用工程材料力学中抗弯梁的力学模型,通过兔胫骨三点弯测试,获得整骨材料力学测试方法实用的力学参数。方法:采用10只正常成年大耳白兔下肢骨标本,共10对胫骨,行三点弯力学测试。作为骨的三维实体模型建立后,虚拟加载的一种实验对比模式。支承跨距为80mm。结果:得到10对正常大耳白兔胫骨抗弯力学参数。胫骨最大载荷所对应的加载点挠度平均值右侧(2.737±0.262)mm,左侧(2.739±0.233)mm;胫骨的最大载荷(代表抗弯强度)的平均值右侧(17.803±2.675)kg,左侧(18.366±
