Abstract

Abstract Using the ABAQUS software, this article presents a numerical investigation on the effects of various stud distributions on the behavior of composite beams. A total of 24 continuous 2-span composite beam samples with a span length of 1 m were examined (concrete slab at the top and steel I-section at the bottom). The concrete slab used is made of a reactive powder concrete with a compressive strength of 100.29 MPa. The total depth of each sample was 0.220 m. The samples were separated into four groups. The first group involved 6 specimens with shear connectors distributed into 2 rows with different distances (65, 85, 105, 150, 200, and 250 mm). The second group had the same spacing of shear connectors as the first group except that the shear connectors were distributed with one row along the longitudinal axis. The third group consisted of six specimens with single and double shear connectors distributed along the longitudinal axis. The fourth group included six specimens with one row of shear connectors arranged in a staggered distribution along the longitudinal axis. Results show that the optimum spacing was 105 mm in all groups and the deflection in group four fluctuated up and down due to the non-symmetrical distribution of the shear connectors.

采用ABAQUS软件研究剪力柱分布对钢-活性粉末混凝土组合梁性能的影响

摘要本文利用ABAQUS软件，对不同螺柱分布对组合梁性能的影响进行了数值研究。共检测了24个跨长为1m的连续2跨组合梁试件(顶部为混凝土板，底部为钢工字截面)。所用混凝土板采用活性粉末混凝土，抗压强度为100.29 MPa。每个样本的总深度为0.220 m。这些样本被分成四组。第一组共6个试件，剪连接件按距离(65、85、105、150、200、250 mm)分成2排分布。第二组剪力连接件的间距与第一组相同，只是剪力连接件沿纵轴呈一排分布。第三组6个试件，单、双剪接头沿纵轴分布。第四组包括6个试件，一排剪切连接件沿纵轴交错排列。结果表明:各组的最优间距为105 mm，而第4组的挠度由于剪力连接件的非对称分布而上下波动;

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation.
