Abstract

Building portals with profile steel construction are very commonly used. However, with the potential for earthquakes in Indonesia which has a very large risk, the geometry of the portal must be given structural elements that can increase the lateral stiffness of the structure. One of the innovations to improve the lateral stiffness of the building portal is to provide a structural element in the form of a shearwall. Steel plate shearwall is one of the structural elements that serve to withstand lateral loads on a building, one of which is earthquake loads. Steel plate shearwall has a high slenderness rate. So that the lateral load will cause a large buckling problem in the shearwall plate. Corrugated steel plate is one of the innovations to solve the buckling problem. The purpose of this study was to analyze the effect of the wave plate shape on the shearwall. This research was conducted using numerical analysis using the ANSYS program to see thebehavior and strength of the steel plate shearwall. The shearwall models analyzed are beam-column frame type, shearwall with flat steel plate, and shearwall with corrugated steel plate, which is given a static lateral load at one end. This study shows that the yield load on the beam-column frame is 1400 kN, the shearwall for the flat steel plate is 1850 kN, and the shearwall for the corrugated steel plate is 2035 kN. The corrugated plate's geometric pattern obtained an increase in yield load of 9% compared to the flat plate. The buckling pattern that occurs in the flat plate shearwall and wave plate is diagonal shear buckling in the center area of the plate.

Abstract

The opening in the castellated steel beam body affects the increase in the flexural capacity and the shear capacity of the steel beam. The research was conducted by determining the span of elements of conventional steel beams and castellated steel beams which have the same length. Steel beams are subjected to two concentrated loads at two points in 1/3 of the span. This study concludes that the effect of the geometric opening on the castellated steel beam will decrease the shear capacity. At the hexagonal opening angle of 45°-50° there is a decrease in shear capacity of about 18%. The optimum shear capacity value occurs at an opening angle of 20° with a decrease in shear capacity of 3%. The failure pattern that occurs is diagonal buckling (buckling due to shear) of the body at 1/3 of the span.

Abstract

Kegiatan pengabdian kepada masyarakat yang dilakukan ini bertujuan untuk pelayanan berupa pendampingan dan sosialisasi kepada pemilik proyek dan pekerja konstruksi pada pembangunan gedung kantor PT. GTN Banjarbaru sebagai pengendalian mutu beton bangunan yang sedang dibangun. Metode kegiatan yang dilakukan adalah pengujian tidak merusak (non destructive test) berupa pengujian palu beton (hammer test) dan ultrasonic pulse velocity (UPV test) di beberapa elemen struktur yaitu elemen poer, sloof, kolom, balok dan pelat. Kegiatan ini melibatkan dosen bidang keahlian struktur pada Program Studi Teknik Sipil dan Program Studi Magister Teknik Sipil dan instruktur Laboratorium Struktur dan Material  serta mahasiswa program studi teknik sipil serta pelaksana proyek. Dari hasil analisis pengujian Hammer Test dan UPV dapat diketahui bahwa seluruh elemen struktur yaitu balok, kolom, pelat, poer, dan sloof memenuhi kuat tekan beton struktural minimal yaitu 17 MPa sesuai SNI 6880:2016 untuk spesifikasi beton struktural. Untuk mengetahui dan mengontrol mutu beton terpasang di lapangan dapat pula dilakukan dengan meminta pemilik proyek dan kontraktor untuk menyediakan sampel kubus beton yang berasal dari pengecoran beton eksisting di lapangan untuk pekerjaan lanjutan seperti balok, kolom lantai atas, dan pelat lantai. Sampel beton kubus ini selanjutnya akan dites umur 28 hari di laboratorium dengan uji merusak yaitu pengujian kuat tekan beton.
