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.

Publisher : Yayasan Ahmar Cendekia Indonesia

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).
