“…However, the investigation on the connections in a bamboo scrimber structure is limited [27,28]. In fact, the connection is often a weak link in a bamboo scrimber structure and so a sound connection design plays a key role in ensuring the integrity, strength and stiffness of the whole structure [28,29]. Therefore, it is necessary to investigate the bamboo scrimber connection in detail.…”

“…Straw-based panels are made of straw or wood and straw mixed in a certain proportion as raw materials, adding resin adhesive, and integrating physical, chemical, electrical, mechanical, hydraulic and other technical principles. Plate products obtained through paving, pre-pressing, hot-pressing, post-sawing treatment, curing treatment, surface treatment and other processes [72,73]. The two kinds of straw-based panels are shown in Fig.…”

Straw is a general term for the stem and leaf parts of mature crops, and is a multi-purpose renewable biomass energy resource in the agricultural ecosystem. The prospect of comprehensive utilization of straw has become broad with the development of agricultural production, the advancement of science and technology, and the improvement of the level of agricultural mechanization. The comprehensive utilization of straw plays an important role in enhancing the sustainable development ability of agricultural economy and improving the current situation of comprehensive utilization of agricultural resources in my country. This paper briefly combs the development history of straw and the prospect and current situation of comprehensive utilization, and expounds the separation technology of straw components, straw man-made panels, straw concrete, straw returning technology and oyster mushroom cultivation. It focuses on the description of the component separation technology of straw and the manufacturing process of straw-based panels. The different separation methods and separation effects of cellulose, hemicellulose and lignin were introduced in detail, and the static yield strength (MOR), internal bonding strength (IB) and water absorption thickness of several common straw-based panels were compared and studied (TS). Finally, it summarizes the benefit analysis of the comprehensive utilization of straw by scholars from the perspective of economics, and summarizes the corresponding measures based on their own views.

“…As the technology associated with reconstituted bamboo has advanced, the basic mechanical properties of this material have been further improved, [1][2][3] it is now widely accepted for use in building structures [4][5][6] . Like other fiber composites, [7,8] reconstituted bamboo is composed of bamboo fiber and phenolic resin bonded together and has the basic characteristics of a viscoelastic material.…”

Reconstituted bamboo is a unidirectional fiber adhesive material with strong temperature sensitivity. The bending strength and deformation of reconstituted bamboo beams at different temperatures were measured using a three‐point bending test. At 10°C, 30°C, and 50°C, the samples showed a brittle tensile fracture, simple tensile fracture, and splintering tensile fracture modes respectively, the bending failure pattern of reconstituted bamboo was intensified with increasing temperature. The results show that with increasing temperature, the degree of interlaminar debonding cracking and longitudinal tensile fracture is aggravated, accompanied by shearing. The ultimate bearing capacity of the reconstituted bamboo decreased from 182.25 MPa to 124.89 MPa (a reduction of 31.47%) and the flexural modulus decreased from 11,329.25 MPa to 8679.90 MPa (a reduction of 23.39%) as the temperature increased from 10°C to 50°C. The temperature has little effect on the initial stiffness, and the postelastic stiffness decreases significantly (by 53.01%) with increasing temperature. The thermal softening effect has a significant influence on the plastic behavior of bamboo. A model of the design value of bending strength considering the temperature was established, and the design value of bending strength was evaluated.
