Abstract

Floor deck merupakan bahan bangunan yang mempermudah pekerjaan terutama pada pekerjaan pelat lantai. Dari segi keefisienan pemakaian floordeck dapat mengurangi volume cor beton dan mengurangi pemakaian besi tulangan cor beton. Pengurangan pemakaian besi tulangan berupa tulangan tarik yang digantikan oleh floordeck itu sendiri. Pada tesis ini akan dilakukan penelitian studi perilaku floordeck komposit baja akibat beban lentur dengan metode elemen hingga, dimana nantinya akan didapatkan hasil seperti nilai kuat momen, gaya geser, dan pola kegagalan sturktur pada pelat lantai. Parameter pengujian ini diambil dari jurnal Lakshmikandhan dkk (2013) yang nantinya akan dikembangkan dengan variasi panjang, dan tulangan. Hasil pemodelan validasi dibandingkan dengan hasil modifikasi dengan besaran beban maksimum dan defleksi yang didapat sebesar 115,54 kN dan 26 mm pada model validasi 1. Sedangkan pada model modifikasi 1 didapat besaran sebesar 77,76 kN dan 28 mm. Pengaruh besar yang terjadi pada model validasi 1 dengan model modifikasi 1 terletak pada shear connector, dimana saat model iv validasi 1 yang dipasang shear connector mengalami kenaikan beban maksimum sebesar 30% serta defleksi mengalami kenaikan sebesar 7%. Model modifikasi yang terdapat 4 variasi panjang, pada model M2 dengan panjang bentang 2500 mm jika di bandingkan dengan M1 dengan betang 1830 mm mengalami penurunan kemampuan momen lentur sebesar 31% sedangkan model M3 di bandingkan dengan M1 mengalami penurunan kemampuan momen lentur sebesar 48% dan pada permodelan M4 jika dibandingkan dengan M1 menggalami penurunan kemampuan momen lentur sebesar 63%. Dari penjelasan diatas membuktikan bahwa panjang bentang floordeck sangat mempengaruhi Momen maksimum, dan gaya geser yang terjadi. Sedangkan kegagalan sturktur pelat terjadi akibat mekanisme lentur dimana tegangan maksimum yang terjadi berada di tengah bentang.

Floor deck is a building material that makes work easier, especially on floor slab work. In terms of efficiency, the use of floor decks can reduce the volume of cast concrete and reduce the use of cast iron reinforcement for concrete. Reducing the use of reinforcing steel in the form of tensile reinforcement which is replaced by the floordeck itself. In this thesis, a research study on the behavior of steel composite floor decks due to bending loads using the finite element method will be carried out, where later results will be obtained such as the value of moment strength, shear force, and structural failure patterns on the floor slab. This test parameter is taken from the journal Lakshmikandhan et al (2013) which will later be developed with variations in length and reinforcement. The results of the modeling on the validation are compared with the modified results with the maximum load and deflection values obtained of 115.54 kN and 26 mm in the validation model 1. While the modified model 1 obtained magnitudes of 77.76 kN and 28 mm. The big influence that occurs in the validation model 1 with the modified model 1 lies in the shear connector, where when the validation model 1 is installed the shear connector experiences a maximum load increase of 33% and the deflection increases by 7%. vi The modified model there are 4 variations in length, the M2 model with a span length of 2500 mm when compared to M1 with 1830 mm stems experienced a decrease in bending moment capability by 31% while the M3 model compared to M1 experienced a decrease in bending moment capability by 48% and at M4 modeling when compared with M1 experienced a decrease in bending moment capability of 63%. From the explanation above, it proves that the length of the floordeck span greatly affects the maximum moment, and the shear force that occurs. While the failure of the slab structure occurs due to the bending mechanism where the maximum stress that occurs is in the middle of the span.
