Abstract

Ferro-gepolymer is a type of thin-wall reinforced element constructed of geopolymer cement mortar reinforced with closely spaced relatively small diameter mesh in layers. In this investigation, the flexural and the deflection behavior of the ferro-geopolymer beams were determined numerically and the results compared to the experimental values. All the experimental material properties adopted for numerical modeling. The numerical model of all the five beams was 600 mm effective span, 100 mm width, and 100 mm height. Each specimen of the beam model having different layers of wire mesh that are 3, 5, 7, 9, and 11. The results showed that the greater the number of layers, the variation between numerical and experimental results follows the same path without much difference. The numerical result showed that the greater the number of layers, the strength was increases but insignificant.

Abstract

The sudden release of energy within earth creates seismic waves on earth’s surface that is earthquake. This research was carried out using a base isolator type of HDR with Certification Number MVBR-0516 (XO.3R) to reduce base shear, displacement and internal forces acting on the structure. This study uses time history analysis method with some earthquake loads in the form of acceleration acceleration. The objectives of the study were to determine the base shear of a reinforced concrete structure building using a base isolator and without using a base insulator. The results of this study indicate the use of base insulators reduces base shear by about 20% -67% and 14% -70.5% for earthquakes in the x direction to the east and west. Meanwhile, in the y direction earthquake, it was around 43% -70% and 43% -62% to the south and north

Abstract

The main principle of designing the multi-storey building is increasing the building strength on lateral force. The higher the building, then the more vulnerable the building in resisting the lateral force, such as earthquake force. In structure design in multi-storey building, there are 2 systems lateral force restraint that often used, that are frame that use shear wall and frame without shear wall. The purpose of this research is to analyze the effect of shear wall placement with respect to structure deflection as an effect of quake load also to find out the sensitivity of the adding the amount of shear wall on decreasing rate of structure deflection as an effect of quake load, that the calculation of quake load effect done by use the Equivalent Static Analysis Method. The result of the analysis obtained the structure deflection decreases with the increasing of the amount of shear wall and the average of decreasing rate of structure deflection for every addition of 1% shear wall is 1.97% also the layout of shear wall placement very react on structure deflection alteration.

Abstract

Column has a function as a successor of the entire building load for foundation with a cross-sectional shape which generally a square. In its development, the shape of column section has begun to vary, namely the 'L', 'T' and 'Plus (+)' shaped sections. The purpose of this study was to determine the effect of restraint parameters such as diameter of stirrups, distance between stirrups, diameter and configuration of longitudinal reinforcement also concrete quality on the capacity and ductility of T-shaped non-square column using Response-2000, XTRACT and SAP2000 programs to ensure the percentage comparison of the analysis result data is not more than 5%. The results of this study for each type of cross-section, namely each increase in the percentage of concrete quality parameters ranging from 25-35 MPa, the diameter of longitudinal reinforcement and diameter of stirrups will increase the value of capacity and decrease the value of ductility, while for each increase in the percentage of parameters the distance between stirrups will decrease the value of capacity and the ductility value. Meanwhile, the variation of longitudinal reinforcement configuration produces T2-1 section as cross section with the largest capacity value and T1-2 section as cross section with the greatest ductility value.
