Mendesain suatu bangunan tingkat tinggi dengan tidak menggunakan plafon dibutuhkan perencanaan yang ekonomis tanpa mengurangi kekuatan dan keindahan dari bangunan tersebut. Balok tinggi berlubang dengan material struktur beton digunakan untuk menghindari terjadinya sistem utilitas pada suatu bangunan tingkat tinggi dengan tidak menggunakan plafon. Balok tinggi berlubang ini ditinjau menggunakan metode Strut and Tie Model (STM). Untuk mengatasi permasalahan yang ada biasanya para perencana merancang daerah D (Disturbed Region) dengan menggunakan konsep pendetailan berdasarkan aliran gaya, sehingga metode strut and tie merupakan pendekatan yang sesuai untuk menganalisis struktur beton di daerah D. Program analisa struktur digunakan untuk melakukan analisis gaya dalam berupa momen dan geser pada struktur beton balok tinggi berlubang. Hasil analisis yang diperoleh pada struktur beton balok tinggi berlubang yaitu bahwa semakin dekat lubang balok dengan tumpuan maka nilai tulangan lentur akan lebih tinggi dan semakin bertambah pula tulangan gesernya.

Abstract

 

Designing a high rise building without using a ceilings requires an economical plan without reducing the strength and the art of the building. The deep beam with holes, which have the structure of concrete materials is need to be used to avoid the utility system in a high rise building without ceilings. This deep beam with holes is reviewed by the Strut and Tie Model (STM) method. To solve the existing problems, planners usually design the D region (Disturbed Region) use the concept of detail based on the flow of force. So the strut and tie method is an appropriate method to analyze the structure of concrete at D region (Disturbed Region). The program of analysis structure is used to analyze the internal forces, which are Moment and Shear, in the deep beams with holes' structure. The result of the analysis in the  deep beam concrete with holes is the more position of the hole is close to its pedestal, the value of the Flexural reinforcement will be more increase, and teh Shear reinforcement will be higher too.
