    The objective of this research project is to perform an analysis of base plate connections in steel structures as a crucial component in building construction, especially in Ecuador where steel structures have gained popularity in recent years. In the framework of the analysis, two main types of base plate connections were identified: a traditional version and another variant with extended bolts that provided greater stiffness, where comparing these two systems, their advantages and disadvantages were evaluated both in constructive and economic terms. A design guide was established that allowed a simple replication of the two systems, seeking to improve the strength and energy dissipation capacity of the structures under seismic loads. After designing each connection based on stresses obtained from a structural design, it was found that the plates with extended bolts functioned as a fuse, generating creep along the bolt, which allowed absorbing stresses without compromising other structural elements; on the other hand, the traditional base plate generated stresses in the column, which could be detrimental after a seismic event. The cost-benefit analysis revealed that plates with extended bolts imply a greater expense due to the complexity of their components and the additional effort required for their installation. Nevertheless, their implementation is recommended in regions with high seismic activity where structural protection is essential. On the other hand, in areas of low seismicity, their use is not economically justifiable, being more convenient to opt for traditional base plates, fulfilling the objectives by proposing a methodology that can be applied in future research and projects, offering a useful tool for the design of base plate type connections in metallic structures that provide safety especially in seismic contexts.
