Abstract

Dalam perancangan beton hertulang dikenal kondisi layan (serviceability) yang membahas lebar retak maksimum yang diijinkan. Lebar retak perlu dibatasi, sehubungan dengan pencegahan korosi terhadap tulangan, keawetan beton dan juga perasaan 'nyaman' bagi pemakai struktur. Peraturanbeton yang ada saat ini, seperti ACI 318-02v dan SNI 03-2847-2002 memperkirakan lebar retak yang terjadi dengan pendekatan ramus empiris dart serangkaian percobaan di laboratorium. Untuk itu, dirasa perlu melakukan suatu pendekatan yang lebih konseptual dalam memperkirakan lebar retak yang mungkin terjadi. Pendekatan yang diambil adalah dengan menerapkan metoda Strut-and-Tie pada balok beton bertulang. Melalui metoda strut-and-tie ini, dapat diketahui tegangan tarik maksimum yang terjadi pada balok yang dibebani. Selain itu dalam metoda ini digunakan perumusan dalam memperkirakan luas penampang saat beton telah mengalami retak yaitu luas efektif Hasil evaluasi dari usulan metoda ini adalah urutan penyelesaian dalam memprediksi lebar retak pada balok beton bertulang, usulan perumusan luas efektif penampang saat beton telah mengalami retak

In designing reinforced concrete, serviceability conditions are known which discuss the maximum allowable crack width. The width of the crack needs to be limited, due to the prevention of corrosion of the reinforcement, the durability of the concrete and also the feeling of 'comfort' for the user of the structure. Current concrete regulations, such as ACI 318-02v and SNI 03-2847-2002, estimate the width of cracks that occur using an empirical formula approach and a series of laboratory experiments. For this reason, it is deemed necessary to take a more conceptual approach in estimating the crack width that may occur. The approach taken is to apply the Strut-and-Tie method to reinforced concrete beams. Through this strut-and-tie method, the maximum tensile stress that occurs in the loaded beam can be determined. In addition, in this method, a formulation is used to estimate the cross-sectional area when the concrete has cracked, namely the effective area. The evaluation results of this proposed method are the sequence of solutions in predicting the crack width in reinforced concrete beams, the proposed formulation of the effective cross-sectional area when the concrete has cracked
