It can be not possible to compute the quantity of reinforcement bar essential for a particular composition as there are many variables which have to be taken into account, including the design strength, the scale and shape of your construction, the soil disorders, and also other local web-site circumstances.
Sambungan susut, yaitu jenis sambungan yang dibuat untuk mengalihkan tegangan tarik akibat suhu, kelembaban, gesekan sehingga dapat mencegah terjadinya keretakan. Jika sambungan susut ini tidak dipasang, maka akan mengakibatkan terjadinya retak acak pada permukaan jalan beton.

Dowel Bars are put during the transverse joints from the concrete ground they usually play a component during the transfer of partial shear load from a flooring to adjacent flooring. Dowel Bar also will allow axial thermal growth and contraction with the concrete slab together the shear axis.
A more practical option to making use of epoxy coating on dowel rods, dowel rod sleeves enable concrete to grow and contract with ambient temperature. This reduces the transfer of tension on elements of the concrete and thus really helps to minimalize the likelihood of cracking transpiring as a consequence of temperature fluctuations.
Dowel bars are used one. To transfer the load from one particular slab to its adjacent slab such that two consecutive slabs go collectively and decrease effects loading formulated because of the slabs by their impartial motion.
Please click on the 1st url beneath to down load the DowelCAD 2.0* software with the supporting “Ground breaking Concrete Pavement Dowel Layout Guidelines” document embedded in the program or the next hyperlink to simply obtain the pointers document:
Dowel besi memiliki kekuatan yang tinggi dan tahan terhadap tekanan dan gaya geser, membuatnya cocok untuk aplikasi yang membutuhkan kekuatan struktural yang besar.
ACI 332-142 usually takes this issue to a far more certain or immediate Dowel Bar degree. Due to the timing of The everyday backfill operation preferred in advance of a basement slab installation, The bottom of the foundation wall is frequently laterally unsupported. Therefore, this code involves both a continuous keyway or perhaps a dowel for use between the footing and foundation wall.

Figure one. Dowel bars (purple steel bars) staying placed at The situation where transverse joints will likely be while in the completed PCC pavement. Listed here, bars are hooked up to “cages”, Dowel Bar that happen to be minimalist bar constructions created to maintain dowels at the correct area ahead of the concrete is paved over them. The cages complete no function in addition to Original alignment aid.

It's the cylindrical hollow tube of 1 close open up and one finish shut with polyehtelene foam fastened into a person end to act as compression filler,which permits enlargement of dowel bars in design joints.
Disamping itu, dowel bar juga memiliki beberapa fungsi penting lainnya dalam konstruksi beton, diantaranya sebagai berikut:
