A review of the evolution of research on proposals for bamboo culms connections in structural systems

Abstract

Structural systems built from raw bamboo have been used for years due to its highly renewable characteristics, versatility, and abundance in various countries, e.g., China, Indonesia, all over South America, and especially Brazil. It is also considered a low specific weight material, which means it is easy to handle and transport. These characteristics make it a low-cost material for building construction. The objective of this systematic bibliometric review is to identify innovations in bamboo culms structural connections in order to contribute to the advancement of technology applied to civil construction by seeking joints that consider the use of industrialized or standardized products. This review revealed there is still no ideal connection capable of solving the great problem of this subject, which points out the need for more studies on the topic. This investigation also allows for the classification of the connections into 5 categories: Bolted connections; Steel member and Steel plate connections; Reinforced Connections with filler; Parameterized connections, and; Connections with the use of wooden dowels.

Advances in Connection Techniques for Raw Bamboo Structures – A Systematic Review

“…Dowelled connections encompass a variety of fasteners, including dowels, bolts, screws, nails, and similar hardware mainly made of metal but occasionally, bamboo, or timber, as defined by Malkowska et al [60]. These connections are favored for their ease of construction, yet they pose challenges such as insufficient joint strength and the risk of splitting or cracking when punching into bamboo culms [72,73]. Consequently, researchers have conducted experimental and theoretical studies to enhance the performance and widespread adoption of dowelled connections [24,27,48,54,60,78].…”

Literature review and preliminary analysis of cassava by-products potential use in particleboards

“…To understand the extent of prior research regarding use of cassava in the construction industry, this research carried out a literature exploration based on the protocols presented by Mandola et al (2020) and Gaffuri et al (2023). These protocols established the criteria for surveying, analyzing, and selecting articles.…”

“…Observing the behavior of by-products in their natural state was understood in this work as a way of simplifying processes to make the intended technology more accessible. To achieve this, BS is guided by the protocol presented by Mandola et al (2020) and Gaffuri et al (2023). The experimental part was carried out in the laboratory following the protocols described below.…”
