The results show that steel tube provide a good confining effect to concrete when the radius-to-thickness(width-to-thickness) ratio is small,that is to say the concrete strength improve larger;the ductility and peak value of Saenz model show better than other models.
结果表明:对于相同等级的混凝土,径厚比(宽厚比)越小,钢管对核心混凝土的约束效应越好,即核心混凝土强度提高越大;Saenz模型的延性好于其他两种模型,应力峰值较大;3种模型中,圆钢管对混凝土的约束效应明显好于方钢管。
In recent years,many methods have been performed to study the stress and constraint effect for both two dimensional and three dimensional models.
其中J-A_2双参数法常用来分析二维模型裂纹端约束效应,而应力商q和离面约束因子T_z理论常用来分析三维模型裂纹端约束效应及厚度效应。
The magnitude of the constraint effect is determined by the strength of the connection.
在空间钢桁架上铺混凝土楼板的结构中,钢桁架上弦与楼板采用连接件相连,楼板通过连接件对桁架在平面内及平面外的变形提供约束,这种约束效应的强弱与连接的强弱有关。
There were restricted effect and incentive effect from organizational climate on employee s informal knowledge sharing decision,the restricted effect was brought into effect by affecting actor s subjective norm,where the incentive effect was by actor s attitude towards knowledge sharing.
结果显示:在员工非正式知识分享中,公平氛围和身份认同氛围具有激励效应,创新氛围和人际关系氛围则具有显著的约束效应,支持氛围既具激励效应,也具有约束效应。
It takes on good restricted effection and elastoplastic properties.
试验结果表明,在钢管混凝土构件的约束扭转受力过程中,钢管与核心混凝土能够协调变形,表现出良好的约束效应和弹塑性形变规律。
Combining the engineering example of Klnbrein Arch Dam 200 m high in Austria,aimed at restriction effect between foundation and arch dam,the 3-D finite element analysis has been carried out.
结合科恩布赖茵拱坝的工程实例,就基础对拱坝坝体的约束效应进行了三维有限元分析,发现施工时预留的陡坎对拱坝坝体应力影响显著,同时建议拱坝施工时地基开挖成概化的地基界面。
The axial force sometimes is so large that the restraints are negative, which hasten the columns buckling, bring the negative restraint effect.
当轴心压力很大时，这种转动约束可能为负，加速柱子的屈曲，产生负约束效应。
