Abstract

Gedung Perkuliahan eksisting terletak di Surakarta dengan luas bangunan 1248 m2 dan memiliki 5 lantai dengan atap baja yang berfungsi untuk fasilitas pendidikan. Dalam tugas akhir terapan ini dimodifikasi menjadi 11 lantai dengan atap beton sebagai gedung perkuliahan dan direncanakan dibangun di kota Surabaya. Berdasarkan hasil Standart Penetration Test (SPT), didapatkan bahwa gedung dibangun diatas tanah dengan kondisi tanah lunak (kelas situs SE) dan berdasarkan fungsinya termasuk kategori risiko IV, sehingga gedung perkuliahan ini dikenakan kategori desain seismik (KDS) D. Analisis struktur menggunakan metode dual system yaitu sistem rangka pemikul momen khusus dan shearwall yang sebelumnya telah dianalisis juga menggunakan metode single system (open frame) serta mengacu pada SNI 03-1726-2012 dan SNI 03-1727-2013. Struktur sekunder berupa pelat dan tangga yang dipikul oleh struktur primer yaitu sloof, balok, kolom dan joint balok kolom serta terdapat shearwall yang berfungsi menahan beban lateral ketika terjadi gempa. Keseluruhan struktur adalah beton bertulang, yang mengacu pada SNI 03-2847-2013. Dari hasil analisa dan perhitungan struktur menggunakan dual system diperoleh dimensi balok induk (B1, B2, B3, B4, B5) 30/80 cm dan B6 35/50 cm, kolom K1 75/75 cm dengan konfigurasi tulangan 16D25 dan terdapat pengecilan pada lantai 5-11 menjadi 12D25, serta dimensi shearwall 30/800 cm dengan tebal 30 cm. Dimensi yang digunakan mempertimbangkan efisiensi dan perioda fundamental struktur yang terjadi. Pada akhir juga disertakan metode pelaksanaan dari pekerjaan struktur kolom dan shearwall. Durasi untuk 1 item kolom K1 dengan volume beton sebesar 2,36m3 adalah ±16 jam dan 1 item shearwall SW1 dengan volume beton sebesar 10,08m3 adalah ±26 jam yang dimulai dari pekerjaan pembesian sampai dengan setting beton dan pembongkaran bekisting. Pada pelaksanaan digunakan bekisting sistem peri untuk mempermudah dan mempercepat pelaksanaan. ============================================================ The existing lecture building located in Surakarta with building area of 1248 m2 and has 5 floors with roof using steel frame that serves for educational purposes. In this thesis, the building modified into total of 11 floors with concrete plate replacing steel frame as roof and planned to be built in Surabaya. Based on the result of Standard Penetration Test, (SPT), it is found that the building is built on soil with soft soil condition (SE class site) and based on its function this building is included in risk category IV, so the lecture building itself is included into seismic design category D. The structural analysis uses dual system method, which is Special Moment Resisting Frame System and Shearwall that previously been analyzed using single system method (open frame) and refer to SNI 03-1726-2012 and SNI 03-1727-2013. The secondary structures like plate and stairways were carried by the primary structure such as sloof, beam, coloumn, and beam-coloumn joint and also shearwall that serves to hold lateral force when an earthquake force. The entire structure is using concrete reinforcement that refers to SNI 03-2847-2013. From the analysis result and structure calculation using dual system, the dimension of primary beam (B1, B2, B3, B4, B5) is 30/80 cm and (B6) is 35/50 cm, the coloumn (K1) is 75/75 cm with the reinforcement configuration using 16D25 and there was reinforcement reduction on floor level 5 – 11 into 12D25, and shearwall dimension is 30/800 cm. Those dimension was considered from efficiency and structure fundamental period. At the end also included the construction method of coloumn and shearwall. Total duration needed per 1 coloumn (K1) with concrete volume of 2.36 m3 is approx. 16 hours and duration needed per 1 shearwall (SW1) with concrete volume of 10.08 m3 is approx. 26 hours starting from reinforcing the concrete, concrete setting time, and formwork dissamble. The construction method of the coloumn and shearwall were using peri formwork system to simplify and faster working operation.
