Abstract

The topography of the Regency of Fifty Cities which varies between flat, undulating and hilly is one of the factors that can cause foundation failure if there is no proper foundation type planning. The construction of the Ribath As Sa'ady Islamic Boarding School is one of the objectives of the RPJP (Long Term Development Plan) of Fifty Cities Regency, namely DP IV (settlement development area). To assist the government in realizing the RPJP, it is necessary to analyze the carrying capacity of the soil to determine the type of foundation that is suitable so that construction failure does not occur. This study uses the CPT (Cone Penetration Test)/sondir test to obtain the Conus Resistance Value (NK) parameter in Kg/cm2 units, and the amount of adhesive resistance (JHP) in Kg/cm units. The two parameters above are recorded for every 20 cm interval to a depth where the NK value is 160 kg / cm2, with a maximum depth limit of 13.80 m from the local soil surface, the recommended type of foundation is the type of deep foundation (Bore Pile)

Abstract

The bridge structure calculation should be carried out in detail and thoroughly. Like any other civil buildings, bridges involve the livelihood of many people. So that a small mistake in planning can be fatal. The Air Koto Ilalang Bridge, which is located on the border of Payakumbuh – Baso, has an important role in connecting Bukittinggi, Limapuluh Kota and Payakumbuh as well as being part of the main connecting route between West Sumatra Province and Riau. Built in 1980, this bridge took a reconstruction in 2020. In this study, an analysis was carried out on the superstructure of the Koto Ilalang bridge with warren type of structure ; loading analysis, calculation of reinforcement for floor plates and the sidewalks, calculating the profile of the transverse girder and the main girder of the bridge. The results show that the bridge floor plate thickness is 30 cm. And the dimensions of the reinforcement on the floor slab are reinforcement 16 – 200 mm at the pedestal and the field. For stringers and transverse girders, steel structure profiles are used IWF 582.300.12.17 as stringers, IWF 900.300.16.28 as transverse girders, IWF 428.407.20.35 as main girders. Meanwhile, the deflection control obtained a value of 1.1224 cm, where this figure is still within the safe limit because the allowable deflection limit is 9 cm.Keywords: Steel, Bridge, Warren Trus, Stringer
