The Four Seismic Analysis Methods at a glance 📐 Seismic analysis methods are fundamental tools in earthquake engineering, allowing engineers to evaluate the structural response of buildings and infrastructure to seismic forces. Each method varies in complexity, accuracy, and computational demands, catering to different design scenarios, structural complexities, and seismic zones. 1️⃣ Equivalent Lateral Force Method This method is one of the simplest approaches for estimating seismic forces. It is widely used for structures with a regular, symmetric configuration and relatively limited height. For such structures, the contribution of the first mode is typically dominant, with the modal participating mass ratio of the first mode shape often exceeding 70-80%, making it acceptable to consider only the first mode shape of the structure. Hence, the loading values are determined by distributing the base shear across each floor based on the first mode shape. This is achieved by defining a static force derived from the properties of the first mode. 2️⃣ Pushover Analysis Method The pushover analysis method is another static method, but also a nonlinear one since it involves applying a static load combined with non-linear analysis. The structure is subjected to unit forces in the shape of the first mode, and the locations of plastic hinges are determined iteratively. The outcome of this analysis is the capacity curve, which reflects the structure's actual performance level. If the structure is irregular or tall—meaning that higher modes play a significant role—the modal pushover analysis should be used. In this case, both the first mode shape and higher modes are considered (like modal analysis). 3️⃣ Response Spectrum Analysis In response spectrum analysis, a force value is derived from the design spectrum for each mode shape, and the analysis is based on this single force for each mode. In other words, the peak response for each mode is considered and combined, even though the modes may not occur simultaneously. 4️⃣ Time-History Analysis This method involves applying time-dependent ground motion records (accelerograms) to a structural model to simulate its response over time. It provides detailed results, including displacements, accelerations, and internal forces at each time step. The analysis can be either linear or nonlinear, depending on the way the material behavior and structural response are accounted for during the loading process. In the linear case, the structure is modeled assuming linear elastic behavior, while in the nonlinear case, the analysis accounts for both material and geometric nonlinearities. Therefore, nonlinear time history analysis is the most advanced approach, capturing the full range of material and geometric nonlinearity under time-dependent seismic loads. 👉 Which analysis you are using for the seismic design? #dlubal #earthquake #seismicdesign #structuralengineering

🔩 Moment Resistance of Steel Connection: Equivalent T-Stub (Component Method) 🆚 Numerical Model Design 📚 Exploring the comparison between manual calculations using the equivalent T-stub method and design results from the Steel Joints add-on, which relies on numerical model calculations, is always fascinating. Both of these methods have a lot in common, and the predicted resistances tend to be very similar. The numerical model takes into account all structural properties considered in the component method. Accurate modeling of component behavior with Finite Element Method (FEM) offers a significant advantage in simulating various geometries of steel connections under diverse loading conditions. This approach is particularly beneficial for tasks that are challenging to analyze manually. 💡 Let's compare these methods on a simple example of a bolted end plate connection to a column under bending moment. The results of the numerical analysis will be compared with the calculation of the moment resistance according to: 'Example C.1 - Bolted end plate connection (unstiffened)' worked out in: 📖 'Joints in Steel Constructions: Moment-Resisting Joints to Eurocode 3 (Publication 398 by SCI and BCSA, https://bit.ly/3WFLSzk)' 📊 First, we will briefly go through the determination of the moment resistance of the connection according to the mentioned literature. Then we will examine the formation of plastic deformation under incremental loading in the numerical model until maximum utilization is reached. We will compare the determined capacities and verify whether plastic deformations in the numerical model occurred at the expected locations. Upon examining the results, we can confirm that both methods lead to almost identical predictions of moment resistance, and the differences are very small. 👍 https://bit.ly/3TDJHtu #RFEM #StructuralEngineering #SteelConnections #SteelStructures #TStubMethod #SteelDesign #FEM #MomentResistance

Exploring Application of Numerical Models in Steel Connection Structural Design Let's delve into this concept with practical examples. In a simple beam model, a steel connection is positioned at the midpoint of the span. We will systematically investigate the maximum utilization of various connection types, analyzing their performance under the influence of bending moments. The evaluation is conducted in accordance with Eurocode regulations. We will monitor the maximum design load applied by a local force at the midpoint of the span, under which the connection ultimately fails. These evaluations will be carried out using the Steel Joints add-on. 🤔 Before watching the video below, challenge yourself!
