Abstract

When the implementation of construction and post-construction of industrial buildings, it is not uncommon for building owners to ask the implementing contractor to add hoist cranes to their industrial buildings, basically the planning consultants in planning a building construction do not take into account the additional burden of hoist cranes beforehand. designing bridge beams, runway beams and corbel, evaluating warehouse building structural elements with an additional 10 ton crane hoist load and designing column reinforcement and gable frames in case of structural failure due to 10 ton hoist crane load. The method used for planning and evaluating the structure uses the Load Resistance Factor Design (LRFD) at SNI 1729: 2015, the loading reference is taken from SNI 1727: 2013. The analysis results show the cross section design of (1) double girder bridge beam with each built up section IWF 600x300x19x25; (2) the runway beam uses a WF 450 x200x9x14 cross-sectional profile; and (3) the console uses an cross-sectional profile WF 300x150x6,5x9, structural elements of the runway beam, lintel beam, and console, which are sufficient to withstand the working internal forces, but on columns and rafters as 1 and as 11 there is an ultimate moment of Mu = 361.34 kN.m while the profile section of WF 300x150x6.5x9 columns and rafters had quite small nominal bending resistance before being reinforced. The rafter reinforcement uses a hounch and a WF 300x150x6.5x9 cut along 3 m, to increase the nominal flexural strength and deflection so that it is able to withstand the ultimate end moment of Mu = 361.34 kNm. While the reinforcement analysis was performed using the concrete steel composite column method, to increase the nominal bending resistance, so as to be able to withstand the ultimate moment Mu = 349.25 kNm. And nominal compressive strength ϕcPn = 3641.22 kN. Keywords: Column reinforcement, Composite column, Composite structure, Crane hoist, Load hoist, Steel structure. Pada saat pelaksanaan konstruksi maupun pasca konstruksi bangunan insdustri tidak jarang para pemilik bangunan / Owner meminta kepada kontraktor pelaksana untuk menambahkan hoist crane pada bangunan industri yang dimilikinya, pada dasarnya konsultan perencana dalam merencanakan suatu konstruksi bangunan tidak memperhitungkan akan adanya beban tambahan hoist crane sebelumnya, Tujuan penelitian ini untuk mendesain bridge beam, runway beam dan corbel, mengevaluasi elemen struktur bangunan Gudang dengan tambahan beban hoist crane 10 ton serta mendesain perkuatan kolom dan gable frame jika terjadi kegagalan struktur akibat baban hoist crane 10 ton. Metode yang digunakan untuk perencanaan dan evaluasi struktur menggunakan Load Resistance Faktor Design (LRFD) pada SNI 1729:2015, acuan pembebanan diambil dari SNI 1727:2013. Hasil analisis didapatkan desain penamapang bridge beam double girder dengan masing – masing penampang IWF built up 600x300x19x25; runway beam menggunakan profil penampang WF 450 x200x9x14; dan konsol menggunakan profil penampang WF 300x150x6,5x9, elemen struktur runway beam, balok lintel, dan konsol, cukup mampu menahan gaya – gaya dalam yang bekerja, namun pada kolom dan rafter as 1 dan as 11 terdapat momen ultimit sebesar Mu = 361,34 kN.m sedangkan profil penampang kolom dan rafter WF 300x150x6,5x9 memiliki tahanan lentur nominal cukup kecil sebelum diberi perkuatan. Perkuatan rafter menggunakan hounch dan potongan WF 300x150x6,5x9 sepanjang 3 m, untuk meningkatkan kuat lentur nominal dan lendutan sehingga mampu menahan momen ultimit ujung sebesar Mu =361,34 kNm. Sedangkan kolom dilakukan analisis perkuatan dengan metode kolom komposit baja beton, untuk meningkatkan tahanan lentur nominal, sehingga mampu menahan momen ultimit Mu = 349,25 kNm.dan kuat tekan nominal ϕcPn = 3641,22 kN. Kata kunci: Beban hoist, Hoist crane, Kolom komposit, Perkuatan kolom, Struktur baja, Struktur komposit.
