Abstract

Rotating machines can be regarded as live load when the machine is operating at a period of time at a certain speed will result in vibration on the structure. The purpose of this research to perform dynamic analysis of the portal structure in order to know how much influence the dynamic load due to the machine that is operating on the structure and get a large ratio of displacement, velocity, and acceleration when the load is given a static and dynamic load. This dynamic analysis is done with the help of SAP2000 V.20.0.2 software. From the results of this study, it was found that the first ten shape modes of the structure did not experience resonance, although in a third mode natural frequency obtained at 57.466 Hz which has a result of 0.865 Hz and is said to be close to resonance, but the frequency does not have much impact on the structure. In addition to considering the resonance value, the structure also considers the value of all amplitudes and the results of the internal forces of the structure. From the results of the amplitude of displacement, velocity, and acceleration shows that vibration does not affect humans and does not damage the structure in accordance with applicable regulations and standards.

Abstract

In the world of construction there are various methods and types of materials used to support the passage of a construction work. One of them is composite girder plate. Composite girder plate is one of the many construction methods that combine two construction materials that are physically different in nature, namely concrete with steel. This type of composite girder plate construction is commonly used for bridge construction work with a fairly large span and width. In its use, of course, it must be preceded by stages of careful planning on a standard and valid basis as well. In the following research will discuss and look for similarities and differences regarding the two types of rules in the planning of composite girder plates, namely the rules of planning composite girder plates using AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS 2017 with SNI 1729: 2015. After doing the initial stages of modeling using CSI Bridge software using the profile cross section constraints of the AASHTO provisions, the internal force obtained is Moment Force (Mu) of 3469.13 kNm and Shear Force (Vu) of 225.98 kNm. Then proceed with the analysis of calculations with the help of Microsoft Excel software namely calculating using the AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS 2017 regulations for stability requirements of strong boundary conditions on the bending requirements. Then a Nominal Moment (ØMn) value of 6420.19 kNm is obtained. Then proceed to calculate the same planning constraints, but this time using SNI 1729: 2015 regulations. Obtained Nominal Moment Value (ØMn) of 6579.88 kNm. Then it can be concluded that the two regulations produce a safe and strong planning, of course in accordance with applicable regulations namely: Moment (Mu <ØMn).

Abstract

United Tractors Company will build a sports center building consist of 3 floors using steel structures. Nowadays, limited land is one of the building development problems. The construction of multi-stored buildings is a solution to the limited land problem. The writer has analyzed beam design with a Wide Flange and Cellular system. Focused on the beam element with construction material in the form of steel with steel quality BJ-37, Fy 240 MPa, Fu 370 MPa. The strength and efficiency of the use of steel tonnage were also analyzed. E-Tabs software 2016 used to steel beam structure analysis. In this beam design planning refers to the steel structure planning following SNI 1729: 2015, SNI 1727: 2013, AISC 2010, ASCE 7-10, and also AISC Design Guide 31. The results of manual verification show that the cross-section of WF 400x200x8x13 and CB 250x125x5x8 with a span length of 6 meters is declared to be strong and safe because fill the strong requirements needs to be smaller than the strength of the plan. The efficiency of the use of Cellular Beam was compared to Wide Flange, the longer of Cellular Beam will increase steel tonnage reductions. The percentage reduction in steel weight will continue to increase when the length of steel usage also increases. This concludes that the use of steel length with steel weight reduction will move linearly. Where in this project with a steel beam length of 1439.27m reduction of steel tonnage was at 19.5%.
