Abstract

AnFen Office Center building is used for office rentals, expected to be a place of business opportunity. The AnFen Office Center building includes office buildings that are used for professional business, administrative or commercial operations. This building has 5 floors with an area of ± 2023,44 m2. The roof of the building is planned using a concrete plate. The shear wall is planned to use the type of l frame wall from the ground floor to the 5th floor which aims to withstand the lateral force caused by the earthquake.Calculation of structures in AnFen Office Center building using SNI 03-1726-2012 for earthquake resistant building count and SNI 03-2847-2002 for construction calculation. Lower structure planning includes pile foundation, pile cap, tie beam, while the top structure includes floor plate, column, beam, roof plate, ladder and shear wall. In the calculation of moments and reactions that work on this building using software SAP 2000 Version 17.2.0.The result of design calculation of floor plate plate with thickness of 20 cm for ground floor plate and 12 cm for floor plate plate 1-5 up to roof plate. Design of beam design with dimensions B1 = 450 × 700, B2 = 300×550. Design planning column with design K1 = 800 x 800. Design planning pile foundation diameter 60 cm at a depth of 12 m.

Abstract

The construction of engineering faculty at the university of moren can be may be able to meet terms of education facilities.Building of engineering faculty university of moren is school buildings, so that including buildings class viii.The building has six floors of with total building area of 11.664 m2.The roof of the building planned use of concrete plate.The shear wall planned in central structure of the floor ground until the floor 5 to hold earthquake force direction x of 7609 kg.m and direction y of 6879 kg.mA structure for the faculty engineering university moren use 03-1726-2012 sni , SNI T-15-1991-03 , sni 2847-2013 , SNI03-1965-1990, and SNI 07-2529-1991.Planning the structure down include the stake , tiebeam , pilecap .While stuktur upper covering concrete plate  , floor plates , stairs, beam , column , and shearwall .In counting the moments and reaction on buildings it uses 2000 v.14 sofware sapThe results of result in planning the plate with thick 20 cm to floor ground and 12 cm pelat 1 until 5 to the floor and the roof .Design planning a beam B1 = 450 x 700, B2 = 350 x 500 , B3 =350 x 600, B4 = 300 x 450.Design planning a column K1 = 800 x 800.Design planning foundation piles 50 cm in the depth 18 meters

Abstract

This research uses Cepu sand fine aggregate as the main material of making of concrete. Cepu sand has high mud and calcium content compared to Muntilan sand.In order for Cepu sand to be used as a concrete material, it is necessary to add an integral waterproofing admixture with plasticizer content to help the aggregate density. This study, varied admixture with 0%, 50%, 100%, 150%, 200% (20ml per 1kg cement) composition. All test objects totaling 80 pieces are used for compressive strength testing with the size of 15 × 15 × 15 cm test specimens.The result of laboratory test showed that Cepu sand concrete without addition of admixture with 14 days drying was found to be the average of compressive strength of 290 kg / cm2, while the highest was obtained by addition of 100% integral waterproofing admixture with an average value of 392 kg / cm2. While on 28 days drying, the average compressive strength value is 352 kg / cm2 without using integral waterproofing admixture, while the highest is obtained with addition of 100% integral waterproofing admixture with average value of 509 kg / cm2. With additional admixture the Cepu sand has increased the compressive strength higher than Muntilan sand concrete.
