Abstract Creep is an important characteristic of bamboo and wood materials
under long-term loading. This paper aims to study the long-term bending behaviour of prestressed glulam bamboo-wood beam (GBWB). For this, 14
pre-stressed GBWBs were selected and subjected to a long-term loading test
for 60 days. Then, a comparative analysis was performed for the effects of pretension values, the number of pre-stressed wires, and long-term load on the stress
variation of the steel wire and the long-term deflection of the beam midspan. The
test results showed that with the number of prestressed wires increasing, the total
stress of the steel wire… More >
