ABSTRACT

This experimental study investigates the response of six innovative moment connections between composite floor panels and glulam columns. Each composite panel consists of five glulam beams and ultra-high performance fibre reinforced concrete cladding. The dimensions of the individual elements of the floor panels and the columns are fixed. The present study focuses on: (i) the experimental investigation (strength and stiffness) of each type of connection, and (ii) the numerical investigation of the connection stiffness capable of reducing the deflection of the middle span. The design criteria of each connection from beam to columns must consider the maximum loading conditions (axial load N, shear load Q, bending moment M) and conform to the design limits. The experimental setup, connection configurations, and material properties are introduced, followed by a detailed account of the test results and observations. According to the results, the innovative connections with fibre reinforced polymer (FRP) bonded rebars (carbon or glass) can reduce the deflection of the floor panel by 45% compared with common bolted connections.

抽象的

这项实验研究调查了复合地板和胶合木柱之间的六个创新力矩连接的响应。每个复合板均由五根胶合木梁和超高性能纤维增强混凝土覆层组成。地板和立柱的各个元件的尺寸是固定的。本研究的重点是：（i）每种连接类型的实验研究（强度和刚度），以及（ii）能够减小中间跨度挠度的连接刚度的数值研究。从梁到柱的每个连接的设计准则必须考虑最大载荷条件（轴向载荷N，剪切载荷Q，弯矩M）并符合设计限制。介绍了实验设置，连接配置和材料属性，其次是对测试结果和观察结果的详细说明。根据结果​​，与普通的螺栓连接相比，采用纤维增强聚合物（FRP）粘结的钢筋（碳或玻璃）的创新连接可以将地板的挠度降低45％。
