Abstract

The aim of this research is to study the effectiveness and the characteristics of structural dynamics of long span RC slab which is stiffened by the addition of steel truss and to verify the numerical analysis results which might be used in the next stage as material of consideration to analyze and design the stiffening method of any prototype or existing structure in need. The experimental works are carried out by using 2 RC slabs with length, width and thickness are 4,6 x 0,96 x 0,05 m respectively, while numerical work shall be carried out by applying structural analysis computer program. The experimental results which are structural dynamic characteristics then will be compared to numerical result.The results of the research show that the behavior of the structure under dynamic loading increased significantly by addition of steel truss, indicated by the increase of structural natural frequency between 15,565% up to 33,33% for several type of truss. The results also show that the average difference between experimental and numerical analysis is 4,503%.

Abstract

Penelitian ini membahas tentang studi perbandingan analisis kolom dengan variasi bentuk penampang kolom yang berbeda antara kolom + (Plus–shaped column)dan kolom beton bertulang berbentuk persegi. Penelitian ini bertujuan untukmenganalisis seberapa besar pengaruh perubahan bentuk kolom terhadap kekuatanstruktur kolom. Perhitungan ini terdiri dari 120 sampel dengan perbedaan mutubeton (fc’), rasio tulangan dan dimensi kolom pada masing-masing sampel.Analisis perhitungan kolom menggunakan hubungan diagram tegangan reganganHognestad. Hasil penelitian, semakin besar rasio tulangan maka selisih nilai Mnkolom + (Plua-shaped column) dan kolom persegi untuk tiap luasan, semakinbesar. Semakin besar rasio tulangan maka selisih nilai Pn kolom + (Plus-shapedcolumn) dan kolom persegi untuk tiap luasan semakin kecil.Kata kunci : kolom beton bertulang, kolom + (Plus-shaped column), rasio tulangan, kapasitas kolom.
