Abstract

In the implementation of construction, the weakening of structure occurs very frequently. This condition is shown through the crack on the plate floor, on the beam or on the column. This structure weakening is frequently caused by wrong design, the change of the function of the building, or natural factor. To maintain the structure of building, reinforcing is very frequently done on the area of experiencing the weakening process.The result of the experiment value was compared through numerical method to obtain the pattern of crack or the increase of load value that can be carried by the beam after being reinforced. That with this simulation, the writer expects that the reinforcement done to the beam especially the one with fricative crack can be accurately and well implemented.

Abstract

Designing on the Waste Water Treatment Plant, often overlooked by variations in water pressure at the time of empty water reservoirs suddenly, so the designing often assumes that the water load is a static load.The case reviewed on the WWTP wall structure is evident that water also has unique behavior especially in large structures. Careful planning certainly will not lead to anything like the case occurring in this research review.The repair or reinforcement analyzed through the Hydro Test testing behavior concludes that without dismantling the entire building, it can still revert to the planned needs of the WWTP building structure.The analysis performed using the finite element method tool to speed up the calculation states that by increasing the number of existing reinforcement can improve the ability of WWTP structure.

Abstract

The construction of bridge and dock abutments generally uses pile foundations, the use of pile foundation is carried out to prevent erosion or movement of land on the surface which can result in loss of bearing capacity or a significant reduction in bearing capacity if carried out using a shallow foundation. The implementation of the pile foundation construction also often experiences a shift in its axle position so it needs to be reviewed the carrying capacity that occurs due to the shift of the axle carrying capacity of the plan. Analysis due to shifting of as-spun pile using the Feld method approach and the Converse-Laberre method as a review of spun pile group bearing capacity efficiency. The bearing capacity of the group pile in the existing condition decreased due to the shift of the pile as far as 1 (one) meter, but it was still within safe limits to carry the burden of the plan.

Abstract

The construction of cantilever retaining wall uses reinforcement as part of the retaining wall’ structure. Reinforcement of the construction of the Retaining Wall is carried out on construction if there is a need for additional reinforcement on the structure or carrying out reconstruction on the structure of the retaining wall. Research on the use of starter rebar uses chemical epoxy, which is used to reconstruct the retaining walls. Soil investigation is carried out because the soil in this structure acts as a load, then this soil parameter is calculated as a lateral force on the wall that makes the rolling moment, and sliding. The land load also acts as a counter weight behind the wall. The study of the use of back reinforcement on the structure of cantilever type retaining wall uses D19-170 as the main reinforcement in the tensile area and D16-170 in the compressed area. Reinforcement for used D13-170.

Abstract

Buildings that use concrete as a structural material are faced with certain compressive strength requirements that are used as design standards. It is a fact that is always found in the field that the quality of the installed concrete cannot always be maintained at the target quality standard. The regulation that becomes the reference for Indonesian concrete standards, namely SNI 2847: 2013 requires that the test standard of core drilling is if the certainty of the low compressive strength value of concrete is known and the calculation results show that the load-bearing capacity is significantly reduced, then the core concrete test (cores) is allowed. taken from the area in question according to ASTM C42M. In such cases, three specimens shall be taken for each compressive strength test which falls below the given value. The test was carried out using a diameter of 4 "and a diameter of 3", respectively, 3 (three) pieces of the core specimen were taken in horizontal and vertical directions. The test results obtained by an average of the three specimens from each variable are as follows, the compressive strength of the concrete taking the core test object in the vertical direction of diameter 4 "is 35.96 MPa, diameter 3" is 32.97 MPa, the compressive strength of the concrete taking the core test object direction horizontal diameter 4 "is 22.93 MPa, diameter 3" is 20.35 MPa. Comparator of the 4 "concrete mixture that was formed produced an average compressive strength of 37.65 MPa.

Abstract

Building structures, especially buildings, are always modified by the designer or building designer during the work. Changes that are made generally always result in an additional excess load from the initial plan on the structural members. The structural part reviewed in this study is a short console beam structure which is given a gradual increase in the load from the target load plan. Console beams are made using reinforced concrete material and formed by forming foundation plates and columns of reinforced concrete as a binding structure for these beams. The test is carried out after the specimen blocks have passed 28 (twenty eight) days of concrete and are given gradual loads until shear failure occurs. The console beam is then reinforced with carbon fiber wrap and is re-treated due to the use of epoxy or adhesive material for carbon fiber wrap adhesive with reinforced concrete. The test was carried out again by adding a gradual load to the failed structure reinforced with carbon fiber wrap. The test is carried out until the specimen fails or collapses. The results of this study conclude that the short console structure which is designed with a cross section size of 100 mm x 200 mm which experiences shear failure also experiences shear failure in its column. The increase in the strength of the short console beam after reinforced with Carbon Fiber Wrap is 83% for Test Object 1 with stirrup reinforcement f 6-150 and an increase of 85% for test object 2 with stirrup reinforcement f 6-100.

Abstract

The AICAR building is part of the waste water system located in Lubuk Gaung - Dumai. Analysis and design of this AICAR uses reinforced concrete material for its structural material. Planning uses the extreme conditions of the water load / hydrostatic load variable. The selection of water load modeling becomes the key word in the analysis and design of the building mentioned above. The hydrostatic load causes the distance pattern from the pile to be limited to a minimum pile distance of 2.57 m x 3.44 m. The reinforcement on the wall has a denser distance than the floor plate reinforcement.

Abstract

Changes in building functions by increasing the number of floors to the top / vertical direction or also called by increasing the number of levels will increase the burden on the pole/ column, and changes by removing one of the pillars to expand the room will add burden to the columns and beams. Impairment of concrete quality after the implementation of structural construction is also a problem that is often encountered in the implementation of construction. Beams, columns, plates are structural elements used to receive and distribute loads. Expenses that are added as a result of changes in the function of the structure, additional load on the building, or not achieving the quality of the concrete plan of the building structure. Stages of testing by forming cylindrical specimens of 15 (fifteen) pieces, with each of 5 (five) specimens carried out without using carbon fiber wrap to represent the conditions of specimens in the field which are below the standard quality plan in this study concrete quality plans carried out using a job mix formula for f'c = 30 MPa, while 10 (ten) other test specimens are carried out by confinement using fiber wrap material. Observations were made by looking at the addition of compressive strength of concrete on the given fiber wrap restraints. Other observations are made by observing the collapse pattern and the mechanism of collapse that occurs with and without the test specimen mounted in restraints. The compressive strength of concrete increased by 54% for typical restraints 1 using standard fiber direction and 23% for typical restraints 2 using the opposite direction of standard fiber. The collapse model of the Test object that is not restrained is by following the standard collapse model in SNI, while the Test object that is restrained experiences collapse after the Carbon Fiber Wrap material is torn due to the addition of compressive load on the Test Object.
