Salah satu inovasi dalam perencanaan dan pelaksanaan pekerjaan kontruksi masa kini adalah penggunaan sistem beton precast diantaranya adalah pelat lantai precast. Penggunaan pelat lantai pracetak yang cukup sering digunakan adalah half slab precast. Pada penelitian ini, akan dilakukan simulasi pemodelan produk pelat lantai dan pelat atap menggunakan sistem half slab precast dengan penulangan one way slab pada fungsi ruko sebagai rumah tinggal dan perkantoran difokuskan untuk wilayah Sumatera Utara dengan 6 jenis tipe pelat, yaitu HS-1, HS-2, HS-3, HS-5 dan HS-6. Dengan simulasi pemodelan ini diharapkan tercipta produk half slab precast generasi Sumatera Utara yang dapat dipasarkan dan memenuhi kebutuhan konstruksi di wilayah Sumatera. Hasil dari penelitian ini yaitu tebal pelat rencana yang mengacu pada nilai minimum diperoleh dari kondisi pelat pada setiap kemungkinan kondisi tumpuan yaitu sebesar 16 cm. Momen terbesar terjadi pada pelat lantai tipe HS-3 dengan nilai momen 1388,45 kgm yang terletak pada tumpuan arah x. HS-3 memiliki dimensi total 650 mm x 300 mm, dengan dimensi half slab perparsial 124 mm x 290 mm. Besarnya lendutan yang terjadi pada pelat lantai dan pelat atap berdasarkan hasil analisis menggunakan software ETABS, memperlihatkan nilai lendutan sebesar 11,633 mm pelat lantai ruko yang difungsikan sebagai rumah tinggal, dan 15,131 mm pada pelat lantai ruko yang difungsikan sebagai perkantoran, serta 15,424 mm pada pelat atap, menunjukkan bahwa tipe baik pelat lantai ataupun pelt atap memenuhi persyaratan lendutan maksimum, sehingga dapat meminimalisir defleksi atau deformasi yang dapat berpengaruh negatif pada kekuatan atau kemampuan layan suatu struktur.

“…Typical seismic retrofitting methods for existing R/C buildings include using various reinforcing materials such as steel braces, precast concrete, and steel plates, as well as increasing the cross-sectional area through pouring. Representative types include the wall construction method, jacketing method, steel plate reinforcement method, and steel bracing seismic retrofitting [3][4][5][6][7][8][9][10][11][12][13]. However, all these seismic retrofitting methods have shortcomings [5,14,15], as listed below:…”

This study proposed a novel V-bracing system equipped with a laterally layered friction damper (LLFD), which can supplement the shortcomings of conventional vibration control systems and is applicable to existing reinforced concrete (R/C) buildings. A material test was used to evaluate the material performance and energy dissipation capacity of this LLFD. Pseudo-dynamic testing was conducted on two-story frame specimens based on an existing R/C building with non-seismic details to verify the seismic retrofitting effects of applying the LLFD V-bracing system to existing R/C frames, i.e., the restoring force characteristics, energy dissipation capacity, and seismic response control capacity. Based on the results of the material and pseudo-dynamic tests, restoring characteristics were proposed for the non-linear dynamic analysis of a building (frame specimen) retrofitted with the LLFD V-bracing system. A non-linear dynamic analysis was conducted based on the proposed restoring force characteristics, and the results obtained were compared with the pseudo-dynamic test results. Finally, for evaluating the commercialization potential of the LLFD V-bracing system, a non-linear dynamic analysis was conducted on an existing R/C building with non-seismic details retrofitted with the system. The seismic retrofitting effect was verified by examining the seismic response load and displacement characteristics, energy dissipation capacity, and damper load and displacement response before and after seismic retrofitting. The study results showed that the R/C frame (building) with non-seismic details exhibited shear failure at a design basis earthquake scale of 200 cm/s2; however, light seismic damage could be expected for a frame (building) retrofitted with the LLFD V-bracing system. At a maximum considered earthquake scale of 300 cm/s2, insignificant seismic damage was also anticipated, thereby verifying the validity of the newly developed LLFD V-bracing system.
