Abstract

This study aims to compare structural modeling with the addition of wall elements and without walls with the help of SAP2000 software. The method used in this study is time history analysis using the San Fernando groundmotion data. Based on the modeling that has been done, the participation of the variance mass has reached 90% for structures with walls in mode 278 while without walls in mode 243. The addition of walls in this study resulted in a decrease in the drift value. The average percentage of settlement of each floor is 40.12% for the X direction and 30.26% for the Y direction. The addition of walls can also reduce the period value of the structure, where the structure with walls has a period value of 1.0804 seconds while the structure without walls is 1 ,2016 sec.   Keywords: Building Structure, Infill Wall, Drift, Time History Analysis

Abstract

This study aims to determine the effect of using kaolin on the compressive strength of mortar compared to normal mortar, as well as to identify the optimum percentage of kaolin that yields the highest compressive strength. The research uses an experimental method with references from journals. The test specimens are made using cube molds with dimensions of 5 cm × 5 cm × 5 cm, totaling 100 specimens. Compressive strength tests will be conducted at the ages of 7, 14, 21, and 28 days.The cement replacement variations using kaolin are 10%, 20%, 30%, 40%, and 50%. The highest compressive strength value occurred at the 10% kaolin variation on day 28, with an average strength of 23.8 MPa. Compared to normal mortar, which has a strength of 23.6 MPa, the increase in compressive strength with 10% kaolin is minimal. Meanwhile, mortar with more than 20% kaolin shows a decrease in compressive strength compared to normal mortar.
