Abstract

ABSTRACTHigh rainfall intensity maybe occur during the dry season. This can certainly disturb the erection of a building project, especially in a case of construction works requiring dry condition, such in concrete item. Various attempts have been made to reduce the height of the puddle, when mixing the fresh concrete in a frame work of sub-structure elements, e.g. the foot-plate foundation. The puddles in the foundry area potentially affect the composition of the mortar especially in water-cement ratio (wcr). This caused a decrease of compressive strength (f’c) of the concrete then causing the quality decreaseof the concrete. This research used two types of mixed concreteconditions: dry and waterlogged condition. The water cement ratioshould be changed when mixing concrete had been performed in waterlogged condition. One determinedcontrol sample was based on a normal concrete mixture with characteristic strength (f'c) = 25 MPa. The standard of concrete mixing used is SNI-2834-2000 on the mixingprocedure of a normal concrete mixed design. The concrete sampleswere tested using a concrete compressor universal test machine (UTM) than comparedto hammer and Ultra Pulse Velocity (UPV) test.Based on the results of the study, the quality of mixed concrete in waterlogged conditions was much lower than the compressive strength design. The percentage reduction in compressed strength of mixed concrete under water submerged conditions ranged from 30.82% to 32.63% to normal concrete compressive strength. The higher level of puddlecaused the lower compressive strength of the concrete.There was a match between the measurements of concrete compressive strength using UTM comparedto hammer and UPV tests.The percentage differences in measurement of hammer test to UTM test results were 10.73% and 9.26% to 21.79% by the UPV test. Keywords: concrete, foot plate, mix design, puddle, wcr Intesitas hujan yang cukup tinggi juga dapat terjadi pada musim kemarau. Hal ini tentu dapat mengganggu pelaksanaan suatu pekerjaan bangunan, khususnya pekerjaan konstruksi yang telah disyaratkan untuk dikerjakan dalam kondisi kering.  Berbagai macam upaya telah dilakukan untuk mengurangi tinggi genangan air pada saat pengecoran elemen sub-structure, seperti halnya pondasi telapak (foot-plate). Genangan air yang terdapat pada daerah pengecoran berpotensi mempengaruhi komposisi adukan khususnya pada faktor air semen (fas). Hal tersebut dapat mengakibatkan kuat tekan beton (f’c) berkurang sehingga mengakibatkan mutu beton menjadi berkurang. Kajian ini menggunakan dua jenis kondisi pengecoran, yaitu: kondisi kering dan kondisi pada genangan air. Faktor air semen berubah seiring dengan kegiatan pengecoran beton dalam kondisi basah (tergenang air).  Satu buah sampel kontrol telah ditentukan berdasarkan adukan beton normal dengan kekuatan karakteristik (f’c) = 25 MPa. Standar pencampuran beton yang digunakan adalah SNI-2834-2000 tentang tata cara pembuatan rencana campuran beton normal. Sampel beton akan diuji dengan alat kuat tekan beton yang dilengkapi dengan dial ekstensometer sehingga dapat diperoleh kurva tegangan-regangan beton berdasarkan variasi fas yang diberikan. Berdasarkan hasil penelitianmaka kualitas beton yang dicor dalam kondisi tergenang air jauh lebih rendah dari nilai kuat tekan beton desain,  Persentase penurunan kuat tekan beton yang dicor dalam kondisi terendam air berkisar antara 30,82% sampai dengan 32,63% terhadap kuat tekan beton normal,  Semakin tinggi genangan air maka semakin rendah kuat tekan beton, Terdapat kesesuaian antara pengukuran kuat tekan beton menggunakan UTM  dengan uji hammer dan UPV, Persentase perbedaan pengukuran uji hammer terhadap hasil uji UTM adalah 10,73% dan 9,26% sampai dengan Kualitas beton yang dicor dalam kondisi tergenang air jauh lebih rendah dari nilai kuat tekan beton desain,  Persentase penurunan kuat tekan beton yang dicor dalam kondisi terendam air berkisar antara 30,82% sampai dengan 32,63% terhadap kuat tekan beton normal,  Semakin tinggi genangan air maka semakin rendah kuat tekan beton, Terdapat kesesuaian antara pengukuran kuat tekan beton menggunakan UTM  dengan uji hammer dan UPV, Persentase perbedaan pengukuran uji hammer terhadap hasil uji UTM adalah 10,73% dan 9,26% sampai dengan21,79% untuk uji UPV.Kata kunci: beton, foot plate, genangan, campuran

Abstract

Stabilitas adalah salah satu pertimbangan utama dalam perencanaan struktur gedung. Begitu banyak kegagalan struktur yang diakibatkan oleh persoalan stabilitas, terutama pada komponen struktur yang menerima beban aksial. Berdasarkan teori dan praktek, jenis tumpuan yang berbeda akan memberikan pola tekuk yang berbeda juga. Perbedaan ini akan berakibat kesalahan dalam analisa beban kritis yang dengan sendirinya menjadi tidak akurat lagi. Pertimbangan keakuratan dan ketepatan dalamprediksi beban kritis ini maka telah banyak perangkat lunak dari analisa struktur yang telah dikembangkan, khususnya analisa tekuk dan SAP2000 adalah salah satunya. Penelitian ini berfokus pada kajian numerik yang berdasarkan pada metode elemen hingga dari sebuah batang aksial tekan yang mempertimbangkan kelangsingan untuk mendeskripsikan kegagalan tekuk. Model pengujian diperoleh dari salah satu sampel penelitian oleh Miftah (2010) yang menggunakan galvanized pipesebagai batang tekan yang dimodelkan sebagai circular hollow section , CHS. Selanjutnya dengan bantuan SAP2000 versi 11,00 akan dibuat pendekatan batang tersebut dengan model frame 3D dan model shell 3D dengan menambahkan spherical dome shell pada ujung-ujung model tersebut untuk kemudan dilakukan analisis dengan analisa statik untuk tekuk linear. Akhirnya kedua model tersebut dibandingkan dan kemudian dari keduanya akan dilakukan verifikasi terhadap nilai eksak (Euler analisis) dan hasil uji eksperimen. Hasil penelitian menunjukkan bahwa dengan melakukan penambahan spherical dome pada ujung-ujung cylindrical shell model akan membuat beba n aksial terkosentrasi pada tumpuan dalam hal ini meggunakan tumpuan sederhana sehingga akan memberikan pola tekuk yang serupa dengan model Euler satu dimensi. SAP2000 versi 11 memberikan ketelitian yang sangat tinggi terhadap hasil analitik yaitu 0,028%. Selain itu, dari kombinasi spherical dome-cylindrical shell pada SAP2000 versi 11,00 juga memberikan ketelitian yang cukup baik yaitu -5,47% dan menunjukkan bahwa dengan model ini beban kritis yang dicapai jauh lebih konservatif dibandingkan dengan menggunakan model frame 3D. Penelitian ini juga menjelaskan bahwa modulus elastisitas meberikan pengaruh yang sangat signifikan terhadap  kesesuaian nilai numeric dan eksperimental yang secara berturut-turut diberikan sebagai berikut 27,76%;35,37%;72,06%
