Building planning in this study is a three-story Islamic boarding school building planning. The building function in this planning is used for the male students' learning building, with planning data based on Permendiknas No. 24/2007. Structural analysis to calculate internal forces on the structure uses two methods, namely the Cross method and the Cantilever Method. The Cross method or also known as the moment distribution method is used to calculate the vertical forces acting on the structure, in the analysis process this method carries out a moment distribution and induction (cary over) of the primary moment (Fixed End Moment) for a number of rounds (iterations) in order to get balance at each knot point. While the cantilever method is used to calculate the horizontal force acting on the structure. The cantilever method is an approximate method for calculating the shear and moment forces developed in beams and columns of a frame or structure due to lateral loads. The applied lateral loads usually include wind loads and earthquake loads, which must be taken into account when planning a building structure. The assumptions used in this method are that the contraflexure points (or the moment diagram inflection points) in the vertical and horizontal sections are located at the midpoint. Abstrak Perencanaan gedung dalam penelitian ini adalah perencanaan gedung Pondok Pesantren bertingkat tiga. Fungsi gedung di perencanaan ini digunakan untuk gedung belajar santri putra, dengan data – data perencanaan berdasarkan Permendiknas No 24 Tahun 2007. Analisa struktur untuk menghitung gaya – gaya dalam pada struktur mengunakan dua metode yaitu metode Cross dan Metode Kantilever. Metode Cross atau biasa juga disebut metode distribusi momen digunakan untuk menghitung gaya – gaya vertikal yang bekerja pada struktur, dalam proses analisis metode ini melalukan distribusi momen dan induksi (cary over) terhadap momen primer (Fixed End Momen) sebanyak beberapa putaran (iterasi) guna mendapatkan keseimbangan di setiap titik simpul. Sedangkan metode Kantilever digunakan untuk menghitung gaya Horizontal yang bekerja pada struktur. Metode Kantilever adalah metode perkiraan untuk menghitung gaya geser dan momen yang dikembangkan dalam balok dan kolom bingkai atau struktur karena beban lateral. Beban lateral yang diterapkan biasanya mencakup beban angin dan beban gempa, yang harus dipertimbangkan saat merencanaan struktur bangunan. Asumsi-asumsi yang digunakan dalam metode ini adalah bahwa titik-titik contraflexure (atau titik-titik infleksi diagram momen) di bagian vertikal dan horizontal terletak di titik tengah.

Active Roll Control System Design With Considering Actuator Constraints for Passenger Car

This paper proposes an active roll control system for passenger cars. The roll actuator with electric motor is expected to replace the hydraulic roll control actuator with the better performance. In order to meet those expectations, highly precise control methods are needed for adjusting the roll motion of the vehicle. In this study, roll dynamics of vehicle and the properties of active roll actuators are investigated first including the latency of the actuator. The identification method is designed to estimate the key parameters of the suspension system. The reference model method is proposed to determine the target roll states and the model predictive control (MPC) method is adopted to control the rolling motion. The roll moment distribution method is also designed between the front and rear actuators considering the load transfer. The proposed control system is validated via simulations and experiments.

Impacts of Implementation of IBS Score Regulations of CIDB on the Concrete Volumes Required for Building Projects in Malaysia

Improvement of construction industry will contribute to the economy of Malaysia because it is one of the five sectors used to calculate the national GDP. This fact is encouraging the Construction Industry Development Board (CIDB) of Malaysia to prepare many development plans like Roadmap 2003-2010, CIMP 2006-2015, and Roadmap 2011-2015. Adoption of the Industrialized Building System (IBS) is the step stone for all these plans. CIDB has created an indicator to assess the degree on industrialization for applied building system; IBS score. Furthermore, CIDB has specified the minimum values of this score for the building projects of government and private sector. This paper discusses the effects of adjusting these values on the structural design of an office building. The CIDB method of calculating the IBS score, the moment distribution method of structural analysis and BS8110 code of design will be used to analyze the selected case study.
