Good Day! I am currently designing a 3 storey building that is to be supported by micropiles. For the preliminary design of the piles, I am looking for recommendations on how to estimate equivalent vertical pile springs to model the supports. For end bearing piles, I estimate the spring using...

Thank you very much for your responses

columns and beams are concrete while all trusses are steel members

Thanks for your inputs. The said roof framing is shown below.

Hi, I am designing a three story building. with the ground floor as a parking area, second floor as an office, and third floor as a gymnasium/court. The building will be designed as a Special moment concrete frame. The columns up to the third floor frame will have beams in both orthogonal...

@slickdeals: Does this also include any column designed as a Moment Frame in two directions or is it exclusive to corner columns?

Hi! The following is taken from ASCE 7-10 chapter 12 Sec. 12.5.4 Seismic Design Categories D through F Structures assigned to Seismic Design Category D, E, or F shall, as a minimum, conform to the requirements of Section 12.5.3. In addition, any column or wall that forms part of two or more...

Okay! Thanks for your input!

I was planning to use spreadsheets for manual computations. Considering that the building is L-shaped causing re-entrant corner horizontal irregularity and will most likely develop Torsional irregularity (possibly extreme torsional irregularity due to length and width ratio being @ 0.25), how...

Hi! I am a new to structural engineering and currently trying design to a four story RC building (Special moment resisting frame) following the provisions from ASCE 7-10 ch 12 for seismic design requirements using Equivalent Lateral Force method in determining the seismic loads. However, the...
