Abstract

This plan aims to plan rigid pavement with a planned age of 20 years with a predicted traffic growth of 4% and the planned concrete quality is K350. In the Rigid Pavement (Rigid Pavement) Planning using concrete paving connected with reinforcement. The planned steel tensile stress is 230 MPa. Reinforcement for the elongated direction used 2 pieces of reinforcement with a diameter of D12-100 mm and for the transverse direction used 2 transverse reinforcement with a diameter of D12-250 mm. Dowels used for rigid pavement planning are 25 mm in diameter, 450 mm long, and 300 mm apart. In this plan used reinforcement with the same diameter for each segment, namely D12-100 mm for longitudinal reinforcement and D12-250 mm for transverse reinforcement.Keywords: Degree of Saturation, Road Performance, MKJI 1997, Traffic Volume.

Abstract

This study aims to determine the extent of the influence of column orientation or direction on the area of reinforcement to be used in building construction. The variables examined in this study were column orientation and reinforcement width. In the first analysis, the column orientation was tried with the X direction plan, so that the column dimensions b = 30 cm and h = 40 cm were obtained. The second analysis tried the column orientation with the Y direction plan, with the same column dimensions in order to obtain b = 40 cm and h = 30 cm. Structural analysis was performed with the help of SAP2000 version 20.2. The results showed that at the same construction with column orientation in X and Y direction, the axial load (Pu) and ultimate moment (Mu) were not much different. These results affect the area of reinforcement obtained from calculations based on the Mu value. The X direction column orientation obtained the value of Pu = -67240.86 Kg and Mu = 4001.97 Kgm with a reinforcing area of 2959.454 mm2. Whereas for the Y direction column orientation the value of Pu = -64776.95 Kg and Mu = 3306.4 Kgm with a reinforcing area of 3055.595 mm2. The percentage value (%) to X is Pu = -3,664%, Mu = -17,381%, and for As = 3,249%.

Abstract

The aim of this study is to redesign the beams and columns of reinforced concrete into a composite structure of Women's Empowerment and Child Protection Agency to derive a comparison of strength and efficiency between concrete-steel composite structures and reinforced concrete structures without changing the layout of columns and beams in the initial planning. LRFD (Load Resistance Factor Design) method and SAP2000 ver.14 as a tool were used in this study. The design was based on Indonesian Standard Regulation. The concrete strength (f’c) and steel strength ( were25 MPa and 250 MPa, respectively. In this study, steel profile BJ 37of WF (400 x 400 x 21 x 21) mm was used for beam and WF (400 x 400x 30 x 50) mm with concrete cross section (500 x 500) mm for column. The results of redesign composite structure for three-story building with the designed steel profile is fulfilled the strength requirements. The obtained maximum moment of beam and column are 36789,36 kg.cm and 43942,2 kg.cm, respectively. The used of composite material is 76,925% more expensive than reinforced concrete material.
