格鲁班（Glubam）胶合竹材作为一种新型建筑材料,研究其耐火性能并与木材进行比较,对胶合竹材单板及杉木单板分别进行了恒温及ISO 834标准升温条件下的单面受火试验,测得了其炭化速率及不同受火条件下试件内部的温度-时间变化曲线。结果表明,胶合竹材的炭化速率低于杉木,其炭化规律与木材相似,即在受火初期炭化层厚度增加较快,炭化速率较大,随时间延长炭化速率逐渐降低,且受火温度越高,材料的炭化速率越大,同时试验测得在标准火灾条件下,胶合竹材受火20 min的平均炭化速率为0.64 mm/min。此外,通过温度场数据的分析比较发现,胶合竹材的传热速率明显低于杉木,其具有优于杉木的隔热性能,且能够满足相关规范对建筑构件隔热性能的要求。

英文摘要：

The paper is inclined to bring about the experimental results of our testing of the constructive member Glubam,a kind of bio-material famous for its energy-saving,bio-degradable and environment-friendly. It is for the above mentioned advantages that it has widely been used in engineering practice,particularly in civil engineering. In order to study its fire-resistant features,we have conducted the constant temperature and the ISO 834 standard fire tests with Glubam by using an electric furnace to obtain the charring rate and analyze the charring mechanism in comparison with cedar-wood. The testing results have provided us with the theoretical basis and the guidance to the engineering practice as well as the reliable experimental data for the relevant norms and regulations. First of all,we have managed to set the thermocouples onto different positions to measure the temperature and time curves at the different depths of the specimen in different testing conditions. Based on the analysis of the experimental findings and results,we have found that the charring rate of 0. 64 mm/min in the 20 min for Glubam under standard fire condition is close to the currently existing testing data for common woods and the fire performance of Glubam turns out to be similar to those of timbers. However,when the charring rate is closer to that of cedar-wood during the initial stage,the charring rate of Glubam tends to decrease with the increase of the fire duration. What is more,the higher the temperature,the higher the charring rate with the faster thermal decomposition of the Glubam. Therefore,in accordance with the temperature field data,the heat transfer rate of Glubam proves to be lower than that of cedar-wood,therefore the heating insulation performance can be regarded as being better than that of cedar-wood. Based on the comparative results of the non-fire surface temperature,it can be concluded that Glubam can better satisfy the insulating demands proposed by the specification.
