Experimental Research And Numberical Simulation On Fire-resistant Performance Of Glubam Structural Wall

With the proposed of green, energy saving, environmental protection andsustainable development, The use of renewable material such as timber as a buildingmaterial gradually becomes the focus. In countries such as Europe and North America,wooden villas are very popular. Especially in Canada and Australia, the design andconstruction of wooden villa started quite earlier. But in our country, due to the largearea of destructive logging in the last century, wood resources are relative deprivation.Even if forest plantation measures could be taken, it is difficult to recover for theLong growth cycle of trees. Therefore, there is a need to find out other materialinstead of increasingly scarce wood, and the bamboo material just satisfiesrequirement.In china, bamboo structure building has a long history. However, it’s not widelyused in building, because of the geometric irregularity and flammability of bamboo.Recently, new processing technology which breaks one of the limitations produces anew kind of bamboo composite materials: bamboo plywood. But there is still alimitation needs further study.Fire-resistant performance of GluBam wall is one of most important factors forGluBam building construction. However, the research is still in the blank. And thispaper is mainly to conduct a full-scale fire test of GluBam wall system under ISO-fireexposure to assess its fire-resistant performance, main influence factors and failuremode. Record the temperature transmission and distribution within the walls and thecharring depth of wall skeleton; Predict the duration of fire resistance; At the sametime, Using fire dynamics simulation software FDS to simulate the gluing bamboowall structure under ISO-834standard fire exposure. The research results show thatthe unexposed surface highest temperature does not exceed90℃, And the temperaturedistribution is closely related to the measuring point location. The failure modebelongs to E class. The duration of fire resistance is more than60min which can wellmeet the requirements of specification. And the fire dynamics simulator, FDS can bewell used to simulate the temperature of GluBam structural member changing alongwith time under fire exposure. The temperature rise trend and distribution ofSimulated fire experiment and fire test are basically consistent. The factors which influence fire-resistant performance of GluBam wall need further study.
