[ID] Dinding geser adalah slab beton bertulang yang dipasang dalam posisi vertikal pada sisi gedung. Dinding geser merupakan salah satu sistem yang berfungsi menjaga kekakuan struktur, maka posisi dinding geser ditempatkan pada lokasi-lokasi tertentu, dengan itu penggunaan dinding geser dapat digunakan secara efektif dalam menahan beban yang diterimanya. Pemodelan struktur gedung dilakukan dengan bantuan software ETABS. Analisis beban gempa menggunakan metode respons spektrum. Pemodelan struktur dibuat untuk gedung tanpa menggunakan dinding geser dan 3 model gedung menggunakan dinding geser dengan posisi yang berbeda. Penentuan posisi dinding geser dilakukan dengan cara uji coba sehingga didapat posisi yang paling efektif. Perhitungan beban gempa mengacu pada pedoman SNI 1726-2012, beban mati berpedoman pada PPURG-1987 dan untuk beban hidup berpedoman pada SNI 1727-2013. Dari hasil perhitungan pada gedung tidak beraturan dengan metode respons spektrum didapat nilai untuk kinerja simpangan maksimum dari 4 model gedung. Simpangan maksimum arah sumbu x pada Gedung tanpa dinding geser sebesar 157,57 mm, pada gedung dengan dinding geser model 1 sebesar 123,41 mm, pada gedung dengan dinding geser model 2 sebesar 125,30 mm, pada gedung dengan dinding geser model 3 sebesar 94,46 mm. Simpangan maksimum arah sumbu y pada gedung tanpa dinding geser sebesar 193,13 mm, pada gedung dengan dinding geser model 1 sebesar 143,79 mm, pada gedung dengan dinding geser model 2 sebesar 141,16 mm, pada gedung dengan dinding geser model 3 sebesar 119,24 mm.  Dari hasil kinerja simpangan maksimum pada Gedung tidak beraturan dengan metode respons spektrum didapat posisi dinding geser yang paling efektif adalah pada Gedung dengan dinding geser model 3 [EN] The Shear walls are reinforced concrete slabs that are installed vertically on the side of the building. Shear wall is one system that serves to maintain the rigidity of the structure, then the position of the shear wall is placed at certain locations, with the use of the shear wall can be used effectively in holding the load it receives. Building structure modeling is done with the help of ETABS software. Earthquake load analysis using the spectrum response method. Structural modeling is made for buildings without the use of shear walls and 3 building models use shear walls in different positions. Determination of the position of the shear wall is done by testing so that the most effective position is obtained. Calculation of earthquake load refers to the guideline of SNI 1726-2012, dead load is guided by PPURG-1987 and for live load is guided by SNI 1727-2013. From the results of calculations on irregular buildings with the spectrum response method obtained values ​​for maximum deviation performance from 4 building models. The maximum deviation of the x-axis direction in Buildings without shear walls is 157.57 mm, in buildings with model 1 shear walls is 123.41 mm, in buildings with model 2 shear walls is 125.30 mm, in buildings with model 3 shear walls is 94.46 mm. The maximum deviation of the y axis direction in buildings without shear walls is 193.13 mm, in buildings with model 1 shear walls of 143.79 mm, in buildings with model 2 shear walls of 141.16 mm, in buildings with shear walls of model 3 of 119.24 mm. From the results of the maximum deviation performance in the irregular building with the spectrum response method obtained the most effective position of the shear wall is the Building with the shear wall model 3

Generally, brick wall (hebel) is considered as non-structural element, which never be counted to bear structural load. But, if carefully calculated, brick walls take part in structure load bearing. In the purpose of reducing the main structural element properties, the brick wall needs to be considered in bearing structural load. In this article, the brick walls modelled as compressive bracings. Using the structure analysis program, the model showed some significant differences in terms of internal force. From the analysis, the differences of moment, shear, axial and torsional force between open frame model (usual model, OF) and compressive bracing (CB) model were 38.17 kN.m; 58.03 kN; 181.75 kN dan 44.18 kN.m, respectively, where the first model had the bigger numbers than the latter model. Displacement of OF model was quite larger than CB model, with the value of difference was up to 85.35% for the X direction structures, and 70.83% for the Y direction. Final properties used for the design are smaller compared than original design, 30/60 to 40/60 for the beams, 50/50 for the columns with the different reinforcements 16-D22 for the second model compared to 20-D22 for the first one. The depth of slab on the second model was 180 mm, slightly smaller than the first model, 190 mm. It can be concluded that using compressive bracing model, structural properties of ITK Integrated Laboratory Building may greatly be reduced, compared to OF model.
