“…Generally, Stepinac et al (2013) concluded that there are three main parameters involved in the above formula, e.g., the diameter of the glued-in rod, glued-in length and interfacial layer shear strength between wood and glue or between glue and rod. Similar to the conclusion above, Stepinac et al (2013) and Yan et al (2016) formulated the Eq. (1):…”

“…The reason were due to the lack of information on the base characteristic of glued-in rod in laminated bamboo. Research by Yan et al (2016) offered information about the effect of the depth and diameter of the glued-in rod on the pull-out strength. Nonetheless, it left many unresearched parameters.…”

“…Researchers have developed formulas to calculate the pull-out resistance of glued-in rod application in wood material. The formula developed by Steiger et al (2006), Yeboah et al (2013) and Yan et al (2016) is usefull to calculate the glued-in rod pull-out resistance with edge distance greater than or equal to the allowed minimum distance. Generally, Stepinac et al (2013) concluded that there are three main parameters involved in the above formula, e.g., the diameter of the glued-in rod, glued-in length and interfacial layer shear strength between wood and glue or between glue and rod.…”

This study aimed to obtain the pull-out resistance parallel to the grain of the threaded steel rod glued-in glubam with various edge distances. The wood structures, both for connection and for reinforcement, used glued-in rods connection. However, there was no research on the application of glued-in-rod into the connection of structural elements from glued laminated bamboo (glubam) due to lack of information on the basic characteristics of the glued-in rod on laminated bamboo. This experiment tested the pull-out resistance and stiffness of the threaded steel rod bounded parallel to the grain in laminated bamboo with varying edge distances. The dimension of laminated bamboo specimens were100×100×100 mm, the threaded steel rod diameter was 10 mm, the drill hole diameter was 14 mm and this research used sikadur 732 as the adhesive. This experiment made eight various edge distances: 1d; 1.5d; 2d; 2.5d; 3d; 3.5d; 4d; and 4.5d, with d as the threaded steel rod diameter and made five replicas of each variation. The results showed that the 3d edge distance or greater had the constant pull-out resistance while less than 3d edge distance had less pull-out resistance. The slip modulus for the threaded steel rod glued-in glubam in this study was not influenced by edge distance with a range 3.732 kN/mm to 7.768 kN/mm.

“…However, the shape of bamboo is that of an irregular thin-walled elliptical cone tube, which has low carrying capacity and large discreteness of mechanical properties, making it difficult to meet the structural requirements of many engineering structures [10,11]. To make more effective use of bamboo, many engineering bamboo materials, such as bamboo scrimber [12], laminated bamboo [13] and bamboo glulam [14,15], have been developed, studied and utilized. Existing research shows that using bamboo engineering materials as flexural members have some unfavorable aspects, such as low section stiffness and insufficient bearing and spanning capacity.…”

A new type of bamboo–concrete composite structure using perforated steel plates as connectors was proposed. To study the composite effect of this new type of composite structure, the slip behavior of bamboo–concrete shear connectors was first studied through push-out tests. Subsequently, four-point bending tests of ten bamboo–concrete composite beams were carried out. The results show that the failure of bamboo–concrete shear connectors occurred between the perforated steel plate and the concrete, and there was no obvious damage between the perforated steel plate and the bamboo. The load carrying capacity of perforated steel plate connectors was relatively stable. The failure mode was moderate failure. Considering the three stages of the load–slip curve, an exponential function is proposed to describe the load–slip curve. The failure modes of composite beams can be summarized as two types. In the first type, the bamboo beam ruptures on the bottom and the concrete dose not suffer significant damage; in the second type, the top surface of the concrete first exhibits longitudinal cracks, and finally, the bamboo beam ruptures. Compared with bamboo beams, the ultimate load of composite beams increased by 1.2–1.5 times, and the sectional stiffness of composite beams increased by 2.9–4.2 times. The equivalent section stiffness was obtained after determining the connection coefficient, and the connection coefficient γb ranged between 0.50 and 0.80 and decreased as the center spacing of the perforated steel plate increased. The equivalent cross-section stiffness obtained by different load stages of the shear slip stiffness was calculated to predict the mid-span displacement. The calculation results show that the effect of slip stiffness on the equivalent stiffness of cross section is not sensitive, and a 35% increase in slip stiffness results in a maximum increase in equivalent section stiffness of only 6%.
