Abstract

bertulang yang diperkuat dua arah yang langsung ditunjang oleh kolom. Dengan tidak adanya balok, gaya geser ditahan langsung oleh hubungan plat-kolom. Hal tersebut berkemungkinan besar mengakibatkan kegagalan berupa punching shear atau keruntuhan geser plat. Selain itu defleksi yang terjadi relatif besar. (Moehle,1989). Pada Tugas Akhir ini dilakukan analisa statistik berupa uji statistik untuk menentukan rata-rata, standar deviasi, dan koefisien variasi dari hasil perbandingan Vc perhitungan berdasarkan ACI 318-14, JSCE Guidline for Concrete No.15 ,Eurocode EN1992-1-1:2004 , CSA A23.3-04, dan SNI 03-2847-2013, dengan Vu yang didapatkan dari jurnal-jurnal mengenai eksperimen punching shear pada flat plate yang tidak diperkuat oleh tulangan geser. Dari hasil analisa didapatkan bahwa rumusan dari Eurocode EN1992-1-1:2004 adalah yang paling mendekati dengan Vexp untuk benda uji sambungan slab-kolom interior dengan nilai rata-rata sebesar 1,119 dan koefisien variansi sebesar 0,179. Sedangkan untuk benda uji kolom interior dengan unbalanced moment dan kolom eksterior rumusan SNI 2847-2013 yang mendekati dengan hasil eksperimen, dengan mendapati nilai rata-rata dan COV dari Vexp/Vc yaitu sebesar 1,08 dan 0,21 untuk spesimen sambungan interior dengan unbalanced momen dan 1,154 dan 0,319. Penulis mengusulkan rumusan prediksi punching shear dengan memodifikasi rumusan ACI 318-14 dengan menambahkan faktor pengaruh rasio tulangan dan didapatkan hasil rata-rata dan COV dari Vexp/Vc sebesar 1,020 dan 0,193 untuk semua tipe spesimen. ================================================================================================ Flat Plate Structure is a kind of structural system which is commonly used on vertical residential building because of some advantages, such as economic structure, has a high aesthetic value, and construction simplicity. Gravity load is one of the aspect that should be significantly considered on the design and analysis of flat plate structure’s behavior. Besides, there are also disadvantages of using flat plate system. With the absence of beams, shear force is solely supported by slab-column joint. This condition could causes punching shear failure on those areas. Moreover, great deflection could occurs on the middle of the infliction. (Moehle, 1989). On this final assignment, statistical analysis will be carried out to determine the average, deviation standard and variance from the result of comparison on Vc calculated using ACI 318-14, JSCE Guideline for Concrete No.15, Eurocode EN1992-1-1:2004, CSA A23.3-04, and SNI 03-2847-2013 with Vu obtained from existing journals about punching shear experiment on flat plate without shear reinforcement . On the next stage, there will be an approach to modify the formula based on statistical test which has the closest result to the experiment on interior and exterior slab-column joint involving possible factor that could affect punching shear analysis. Based on the results of the analysis, it can be said that the formula from Eurocode EN1992-1-1:2004 has the closest result on the test object with Vexp for interior slab-column joint having the average amount of 1,119 and variance of 0,179. Whereas, for the test object on interior column with unbalanced moment and exterior column, the formula from SNI 2847-2013 has the closest result toward the experiment having the average and coefficient of variance of Vexp/Vc consecutively 1,08 and 0,21. For the interior joint with unbalanced moment, the average result and coefficient of variance are consecutively 1,154 and 0,319. The author proposed a predictive formula for punching shear by modifying the formula from ACI 318-14 by the way of adding influence factor of reinforcement in order to obtain the average result and coefficient of variance from Vexp/Vc respectively 1,020 and 0,193 for all specimen types.
