STUDI ANALITIKAL PERILAKU DAN KINERJA STRUKTUR RANGKA DINDING PENGISI (RDP) DENGAN VARIASI KETEBALAN DINDING
ABSTRAK Studi analitikal ini dilakukan untuk mengevaluasi efek dari ketebalan dinding pada struktur rangka dinding pengisi (RDP) sebagai struktur penahan beban gempa. Analisis perilaku dan kinerja struktur perlu dilakukan sehingga diperoleh struktur yang aman bagi penghuni bangunan jika terjadi gempa yang kuat. Metode pemodelan divalidasi terhadap hasil uji laboratorium peneliti lain. Hasil validasi menunjukkan bahwa kurva beban-simpangan dan tegangan model RDP menggunakan metode strat diagonal dan elemen shell, serta analisis statik pushover sudah mendekati hasil uji laboratorium. Metode pemodelan tersebut diaplikasikan pada model struktur gedung hotel 3 dan 5 lantai dan dianalisis linier dan nonlinier statik pushover menggunakan software SAP2000. Struktur gedung 3 dan 5 lantai dibuat dengan ketebalan dinding yang sama 150 mm setiap tingkat (M3TF dan M5TF) dan tebal yang bervariasi (M3TV dan M5TV). Ketebalan yang diperoleh pada struktur M3TV dari lantai atas hingga bawah yaitu 150 mm, 250 mm, 300 mm dan untuk struktur M5TV yaitu 150 mm, 200 mm, 250 mm, 300 mm, 350 mm. Hasil analisis menunjukkan bahwa model RDP dengan variasi ketebalan dinding memiliki perilaku dan kinerja yang lebih baik dibandingkan tanpa variasi ketebalan dinding baik 3 dan 5 lantai, dilihat dari perubahan kinerja struktur dari B-IO (dapat segera dihuni) menjadi B (operational level). Model M3TF dan M5TF mengalami sendi plastis pertama pada dinding lantai 1, sedangkan M3TV mengalami sendi plastis pertama pada balok lantai 1 dan M5TV mengalami sendi plastis pertama pada balok lantai 1 sampai 3. Hal ini menunjukkan model RDP dengan variasi ketebalan dinding terhindar dari kegagalan soft story, sehingga variasi ketebalan dinding sangat diperlukan. ; ABSTRACT This study was conducted to evaluate the effects of variations in wall thickness of the infilled frame structure (RDP) as an earthquake-resistant design in order to obtain a structure that is safe for building occupants once a strong earthquake occurs. Validation model has been done based on the results of other research laboratory tests using the method of shell element and diagonal strut. The results of the validation model showed that the load-displacement curves and the stresses on the wall of the RDP were able to mimic the test results. Those methods were then applied to 3 and 5 storey hotel buildings with RDP and were analyzed with linear and non-linear static pushover using SAP2000 software. Building structures of 3 and 5 storey (M3TF and M5TF) were created using the same wall thickness of 150 mm and also with varying wall thicknesses (M3TV and M5TV). The wall thicknesses obtained for M3TV from top to bottom level were of 150 mm, 250 mm, 300 mm respectively, while M5TV models were of 150 mm, 200 mm, 250 mm, 300 mm, 350 mm. The analysis results showed that the RDP models with variations in wall thickness had better behaviour and performance than those without variations in wall thickness for both 3 and 5 storey structures. This can be seen based on changes in performance from B-IO (immediate occupancy) to B (operational level). Models M3TF and M5TF experienced the first plastic hinge on the first-floor walls, M3TV was on the first-floor beam, and M5TV experienced the first plastic hinge on the first to third-floor beams. These show that the RDP models with variations in wall thickness are safe from soft-story failure. Thus, variations in wall thickness in the RDP model are necessary.
