Abstract

Cross laminated timber (CLT) construction system turns out to be relevant in Chile for medium-height buildings due to its earthquake-resistant behavior. To establish the feasibility of the system in Chile, its fire resistance in walls and slabs was analyzed. The wooden elements that are subjected to fire conditions have a slow rate of carbonization, which generates a "protective" thickness. Fire resistance is defined as the time in minutes in which a structure can withstand the conditions of a standardized fire test. Chilean regulations require the use of an "Official fire behavior list" for construction elements, in order to demonstrate that an acceptable level of safety is reached. Those solutions that are not included in the Official Fire Behavior List must be accredited through an official test. The objective of this work is to obtain the fire resistance of wall and slab element manufactured in radiata pine CLT, under the requirements of the NCh935 / 1.Of97 standard.
