Abstract

The foundation is a substructure which functions to support the loads and forces caused by the superstructure (superstructure) to the soil layer which will carry these loads and forces. Deep foundations are usually used to obtain a large enough soil bearing capacity and if the depth of the hard soil is far below the ground surface. The aim of this task is to analyze the bearing capacity of pile foundations using sondir data, standard penetration test (SPT) data, as well as the finite element method using the plaxis program. The method used in this final assignment is by studying literature, then collecting the necessary data, and after that carrying out calculation analysis using existing methods. From the results of the calculations carried out, different results were obtained. Where for sondir data at point S1 obtained Qu =115.80 tons; at point S2 obtained Qu = 104.80 tons; at point S3 obtained Qu = 105.50 tons. Meanwhile, based on SPT data at point BH-01, Qu = 398.23 tons, and using the plaxis program Qu = 425 tons

Abstract

Research on the use of beach sand as a fine aggregate in concrete is due to the abundance of beach sand in the area. This research was carried out to analyze sand and find out how much compressive strength is produced when sand is treated without being washed with sand that is treated with washing, so that from this research the local community will know and can use it as a building material. The sand used is Pondok Permai Beach Sand, Pantai Cermin District, Serdang Bedagai Regency. The planned compressive strength of the concrete is 21.7 Mpa with 40 cylindrical test objects. Tests for compressive strength of samples were carried out at ages 7, 4, 21 and 28 days and each treatment was given 5 concrete samples. This research only focuses on beach sand concrete. The analysis results show that this beach sand is included in zone IV sand, namely sand with fine grains. The average compressive strength test results of concrete for sand not treated with washing and treated with washing at age 7 were the same, namely 16.22 Mpa. For compressive strength aged 14 days, concrete with sand that was not treated with washing produced a compressive strength of 15.58 Mpa, while concrete with sand that was treated with washing reached 17.44 Mpa. For compressive strength aged 21 days, concrete with sand that was not treated with washing produced a compressive strength of 16.10 Mpa, while concrete with sand that was treated with washing produced a compressive strength of 18.55 Mpa. In the compressive strength test aged 28 days, concrete with sand that was not treated with washing produced a compressive strength of 17.33 Mpa, while concrete with sand that was treated with washing produced a compressive strength of 19.55 Mpa. From the results of this research, the researchers concluded that the fineness of sand influences the compressive strength of concrete and washed sand can increase the compressive strength of concrete.

Abstract

Non-destructive tests are currently widely used in evaluating the quality of concrete installed in the field. One NDT is using the Ultrasonic Pulse Velocity (UPV) method. In general, the use of UPV in concrete is to estimate concrete strength, determine the homogeneity of concrete and detect concrete damage, for example the presence of voids or cracks. This research is intended to determine the accuracy of UPV test results in detecting concrete cracks at several variations in crack depth. In this research, the UPV tool validation process was carried out by making 1 type of test object. Namely 1 beam specimen for testing crack depth (UPV) with 6 variations of artificial cracks where the artificial cracks are made using plywood. Each sample has been treated so that it can describe the crack depth according to the existing plan. In testing, it was found that the estimated crack depth in variation I was 33.2 mm deep, variation II was 18.8 mm deep, variation III was 104.4 mm deep, variation IV was 115.8 mm deep, variation V was 24.4 mm deep and variation VI 159.3 mm deep. And the average accuracy is 13.60%. The smaller the wave travel time, the smaller the crack depth, the smaller the wave emission and the longer the wave path to detect cracks. which means that the accuracy of UPV crack depth testing tends to decrease with the unevenness of the concrete surface.

Abstract

An anchor is a steel element that is embedded in concrete when it is cast (cast in place) or installed later (post-installed) into concrete that has hardened and is used to distribute loads (tension and shear) acting on the concrete (SNI 2847:2019). The use of anchors in the world of construction is increasingly popular to help connect concrete structures. The installation of anchors has progressed from the initial anchors being installed before casting the concrete (cast in place), progressing to the anchors being installed after the concrete has hardened (post installed) by drilling. By drilling into concrete, installing and removing anchors becomes easier. Installation of cast-in-place anchors is generally used in the design of new construction, while post-installed anchor installation is generally used in old construction for repairs or retrofitting. Anchors have several variations including hed heax, L bolt and J bolt anchor variations, but it is not yet known which anchor variation has a greater bond strength value, what are the results of the comparison of bond strength values ​​for each variation of anchor and what are the differences in the anchor bond strength capacity for each variation? the anchor. With this research, it is hoped that we can find out the bond strength and bond stress values ​​for each variation of anchor so that the comparison of the bond strength of the anchor can answer the differences in capacity of each variation of the anchor as well. Research on the bond strength of anchors based on variations in anchor shape using the cast in place method shows that the bond strength value shown at the highest loading value is the type J anchor variation with an average load of 27,816 kN, the type L anchor variation with an average load of 26,971 kN and variations of the hex head type anchor with an average load of 12.85 kN. It can be concluded that the stress value is directly proportional to the loading value. The greater the loading value, the greater the bond stress value. The highest bond stress value is found in the type J anchor variation with an average bond stress value of 151,397 Mpa, in the L type anchor variation with an average bond stress value of 147,798 Mpa and in the hex head type anchor variation with an average bond stress value of 69.953 Mpa, so the bond stress is directly proportional to the loading value.
