“…The use of FEA has been the preferred method to study the behavior of concrete (for economic reasons). Many studies investigated the feasibility of the use of finite element analysis in order to investigate the behaviour of reinforced concrete elements [1][2][3][4][5]. Willam and Tanabe [6], contain a collection of papers concerning the finite element analysis of reinforced concrete structures This collection contains areas of study such as: the seismic behavior of structures, the cyclic loading of reinforced concrete columns, the shear failure of reinforced concrete beams, and concrete steel bond models.…”

Experimental testing was used widely as a means to investigate the behavior of these individual elements and the effects of concrete strength under different loading types. While this method represents real life responses, it is very time consuming and the use of materials can be quite costly. Recently, the use of finite element analysis (FEA) has increased due to advances in knowledge and the capabilities of computer hardware and software. The utilization of computer software to model the structural elements has become much faster and extremely cost-effective. The finite element software ANSYS 11.0 is used for modeling and analysis by conducting non-linear static analysis. This research work used nonlinear finite element analysis for a reinforced concrete beam in order to show the potential of the FEA for studying the behavior of reinforced concrete elements, and to understand their load-deflection response along with the crack evolution. For concrete a solid 65 element was used, while for the reinforcement steel bar link 8 elements were used. For the material constitutive model linear and multi-linear behavior for concrete were considered, while linear and bilinear behavior were considered for the reinforcement bar. A reinforced concrete beam model is studied and compared with experimental data from the literature. The characteristic points on the load-deflection response curve predicted using finite element analysis, were compared to the theoretical limit (hand-calculated) results. Conclusions were then drawn as to the accuracy of using finite element modeling for the analysis of reinforced concrete elements. The results showed a good match to experimental and hand calculations.

“…The finite element method, on the other hand, can take all relevant parameters into account. For this reason, the finite element (FE) method has been increasingly used to simulate flange joints in recent years [25][26][27][28][29][30][31][32], and the results have been used to improve analytical models, among others. FE analysis is also used in this paper as a reference method to determine the realistic bolt load in the discussed flange joint.…”

The influence of the working load on the dynamic loading of the bolt was investigated in our study for two cases of flange joints. The analytical calculation according to the Verein Deutscher Ingenieure (VDI) 2230 recommendation and the numerical analysis using the finite element method (FEM) were performed for a model of a four-bolt joint. To verify the FEM analysis, the forces in the bolts were measured during preloading and during the application of the working load on the test rig. Based on the analytical and numerical results, the influence of the working load application point on the bolt load and its fatigue life was analysed for different cases. Comparison of the results shows that the analytical method overestimates the additional bolt stresses at low working load, mainly due to the extremely large fraction of bending stress. As the working load increases, the differences between the two methods decrease, but only for the reason that the analytical method can only linearly scale the overestimated results at lower working load, and FEM analysis, on the other hand, shows a progressive increase of the additional stress in the bolt at higher working loads due to the spreading of the flange. It is also shown that a high washer significantly increases the fatigue life of the bolt for two reasons: (i) a high washer reduces the additional stress in the bolt, and (ii) the high washer shifts the critical fatigue point from the thread area to the transition of the bolt shank to the head.

“…Selain tes secara eksperimental yang dapat dilakukan pada sambungan, test secara analisis non-linier dengan metode elemen hingga yang berbaris komputer juga menjadi alternatif yang sudah banyak digunakan untuk meninjau perilaku sambungan. Penggunaan dengan metode elemen hingga non-linier dapat memperluas interpretasi untuk membandingkan hasil dan observasi penelitian eksperimen yang telah dilakukan sebelumnya oleh Mohammed et al [7].…”

Post-earthquake building failure or collapse is determined by the quality of the connection. The selection of the right connection is very necessary to ensure the occurrence of plastic joints in the beam area. This study discusses the behavior of Extended End Plate type steel connections when given cyclic loads using software based on ABAQUS 6.14. This study will do modeling which then results will be compared from moment -rotation, rotational stiffness value and failure mode using software based on ABAQUS 6.14. The modeling used I-Shaped welded plate for column dimensions 300×250×8×12 mm and beam dimensions 300×200× 8×12 mm, column stiffness thickness 12 mm, thickness of 10 mm extended end plate stiffener. The results of the modeling above when compared with the results of the experiments used do not have a significant difference. The modeling results with the auxiliary program finite element is an approach so that the results are not exactly the same as the results of the experiments conducted. Based on the results of the modeling performed, modeling on the joint has good ductility.Kata kunci: Pembebanan siklik, plat ujung tambahan, metode elemen hingga, sambungan baja Abstrak Kegagalan atau keruntuhan bangunan pasca gempa ditentukan oleh kualitas sambungan. Pemilihan sambungan yang tepat sangat diperlukan untuk menjamin terjadinya sendi plastis pada daerah balok. Studi ini membahas tentang perilaku dari sambungan baja tipe Extended End Plate saat diberi beban siklik dengan menggunakan software ABAQUS 6.14. Hasil eksperimental berupa momen-rotasi, nilai kekakuan rotasi dan adanya mode kegagalan akan dibandingkan dengan pemodelan yang dilakukan pada program ABAQUS 6.14. Pemodelan yang digunakan welded plate I-Shaped dengan dimensi kolom 300x250x8x12 mm, dimensi balok 300x200x8x12 mm, ketebalan pengaku kolom 12 mm dan ketebalan pengaku extended end plate 10 mm. Hasil pemodelan yang sudah didapat jika dibandingkan dengan hasil eksperimental tidak memiliki selisih yang signifikan. Hasil pemodelan dengan program bantu finite element merupakan sebuah pendekatan sehingga hasilnya tidak sama persis dengan hasil eksperimen yang dilakukan. Berdasarkan hasil pemodelan yang dilakukan pemodelan pada sambungan memiliki kemampuan daktilitas yang baik.
