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

Concrete test materials received in the field were treated and tested at the age of 28 (twenty eight) days, regulated in the Indonesian National Standard for concrete with the standard number SNI 2847: 2013. In addition, the equally important standard to be observed in concrete testing, especially in construction, is the observation of the shape of the collapse of the test object, which was written in the SNI 1974: 2011 concrete regulation. This collapse model needs to be considered because it can pay attention to the possibility of errors in testing. The test object used in this study was formed using Self Compacting Concrete type concrete. This type of concrete is an innovative concrete that does not require vibration for compaction. Because this concrete can flow by itself and actually fill the formwork until it reaches full compaction. These concrete collapse models must be considered because they are very interesting to see. Researchers conducted experiments on concrete collapse models made using several variations of concrete mixtures, ranging from variations in water content (standard, -5%, -10%, + 5%, + 10%), height variation of the test object (15 cm , 12.5 cm, 10 cm, 8.5 cm, 7.5 cm), and variation in age of the plan. From the research conducted by researchers, the number of specimens carried out shows the pattern of collapse of the crack model parallel to the upright axis, then there is the model of cone and shear failure and the least is the cone and split failure model.

Abstract

It is commonplace when architectural designs that require beauty often do not pay attention to the strength of building structures as part of a unity of structures and architecture of buildings, forgetfulness of the part of the building that was originally assumed not to bear the burden in the end should bear the burden causing a new design adjustment. The study of pipe columns as poles on cantilever building structures was studied because of the concerns of the building owner and also the construction executor of the cantilever frame design. The position of the pole as a successor to the load from the roof to the foundation is noticed because the steel material is elastic and also weak against buckling. An examination of the modified section of the frame structure is absolutely necessary to increase the stiffness of the structure, so that the pipe columns with small dimensions according to the architectural design can be maintained.

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

Vibrations on the floor plates of multi-storey buildings can occur due to excitation arising from the activities of human activity such as running, dancing and other sports. Vibrations become excessive on the multi-storey building floor system, and this vibration is not related to the building's safety factor, but only in contact with the user's inconvenience. Excessive vibrations occurring in the system of floor plate structure may occur in multi-storey buildings that have (1) lightweight floor structure systems due to the use of high-grade building materials or composite materials on building structural elements such as beams that allow the design of the elements of the structure (2) long-stretched floor plate system with low structural stiffness in which the dominant natural floor frequency tends to be low and close to excitation frequency, and (3) the floor plate structuring system has a low damping value due to the use of the partition and fewer furniture items. The three things mentioned above cause the vibration on the floor plate system to be excessive and cause discomfort and disruption for users of the building. Vibration on the floor plate system causing the discomfort may occur on a floor plate system that has a vibration frequency (fn) of less than 8 Hz. To reduce the vibration frequency (fn) of the plate system must be increased to approximately 8 Hz natural frequency. The use of WF-shape steel structure used is WF 200, capable of increasing the damping value in the system of floor plate structure which is observed in one of the school buildings in Medan.

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.

Abstract

The use of Carbon Fiber Wrap, continues to increase along with increasing research on the ability of this type of material to provide restraints that can increase the ability to bear the burden given. Carbon Fiber Wrap used has a standard use of unidirectional fiber, which is the use of unidirectional fibers. The study used concrete material using 20 (twenty) samples aimed at finding out how much influence the implementation did not follow the standards and conditions for using Carbon Fiber Wrap. Tests carried out using cylindrical specimens with a diameter of 10 cm and height of 20 cm. As comparison, 5 (five) test specimens were not installed with Carbon Fiber. The test results obtained from 5 (five) specimens using epoxy chemical before and after installation of Carbon Fiber on the specimens with unidirectional fibers add concrete compressive strength by an average of 56%. As many as 5 (five) specimens using chemical epoxy before installing Carbon Fiber on the specimens with unidirectional fibers, increased the compressive strength of concrete by an average of 26%. And as many as 5 (five) specimens using epoxy chemical before and after the installation of Carbon Fiber in the opposite direction of the perpendicular fiber the fiber adds an average compressive strength of only 18%. Other observations from this study were obtained on the difference in collapse of specimens mounted with Carbon Fiber Wrap as a result of specimens which were not fitted with Carbon Fiber Wrap. The collapse does not form a shear or normal failure pattern on the test object but the concrete of the test object is destroyed by damaging and tearing the Carbon Fiber Wrap.
