General Objective: The present research project seeks to experimentally study the seismic behavior of exposed plate connections with extended anchor bolts through large-scale laboratory tests that complement the numerical and analytical studies that exist in this regard [21 and 23]. Furthermore, it is proposed to examine the effect of incorporating the ductile behavior of this connection in the overall response of steel buildings.
Specific objectives:
- Study the cyclic behavior of plate-base connections with extended bolts (EBP-EAB) by developing a large-scale experimental program. Details of the experimental program are described in steps 1 to 5 of the methodology, and a period of 5 months is planned for the execution of the 7 scheduled trials. Specific details of the trial are indicated in Figure 3.
- Develop a methodology for the design of the plate-base connection with extended bolts, based on the results of laboratory tests, and computational models of the connection calibrated with the experimental information obtained. Details to achieve this objective are described in steps 6 and 7 of the methodology, and it is estimated that this stage will last 2 months.
- Quantify the effect of incorporating the proposed connection detail on the performance of steel buildings. Details to achieve this objective are described in step 9 of the methodology with an estimated time of 2 months.
- Generate two scientific articles in high-impact indexed journals (Q1), as well as present at a relevant international conference. The first publication will present the experimental results and the design methodology, while the second will quantify the effect of incorporating the hysteretic behavior of the connection in the global response of steel buildings.
