SUMMARY
MUSTIKA JONI, 1710246320, NUMERICAL ANALYSIS OF LIGHTWEIGHT
BRICK DUE TO HIGH TEMPERATURE USING LUSAS V.19, supervised by
Reni Suryanita and Harnedi Maizir.
The use of a material greatly affects the thermal comfort of the building, so that
the use of light brick material is recommended in the tropical climate. Therefore,
it is necessary to carry out a Numerical Analysis of the thermal properties, is
called distribution of heat transfer in lightweight bricks. The analysis used a finite
element method to LUSAS v.19 and was verified using the Wickström method.
LUSAS is a finite element method that can be used to analyze in detail the
structure and temperature transfer, which consists of three main stages;
modelling, running the analysis, and seeing the results of the analysis. This study
aims to analyze the distribution of heat transfer in lightweight bricks with certain
temperature and time variations due to the application of high temperatures. The
results of the analysis are in the form of contours and temperature distributions
which will be compared with the results of the Wickström method, which is a
method for calculating the temperature of middle span of the lightweight bricks
exposed of high temperature. In this study, the used input data are material
geometry, density, thermal conductivity, and specific heat capacity. While the load
given is high temperature with exposure time and review points in x and y.
The results of the comparison of the distribution of heat transfer between
Wickstrom and the LUSAS v.19 program was that the temperature of heat transfer
using the LUSAS v.19 program was higher at the beginning, but if high exposure
was carried out for a long time the value of heat transfer using the Wickström
method was higher than using the LUSAS v.19 program. The percentage of heat is
inversely proportional to the type of mass, while the speed of heat transfer is
directly proportional to the type of mass material. Temperature at 1. 000 ℃ with a
density of 840 kg/m3 for 2 hours of exposure, the heat transfer that occurs at the
review point using the Wickström method is 942,912 ℃ and the LUSAS v.19
program is 931.148 ℃. This shows that the accuracy of these two methods is
98.752 %, so this method can give contribution to builders/planners in carrying
out the design processed by considering the factors of thermal comfort in the
building.
