Hi. I can provide structural design services for your project. I am proficient in structural analysis, design, and detailing of reinforced concrete, timber, and steel structures, I have worked with international codes such as the ACI, AISC, Indian, and Australian codes. I am skilled in analysis software, including Sap2000, Etabs2000, Safe, Staad Pro, and Adapt Builder.
I can deliver any phase of structural engineering work, including analysis, design, drafting, documentation, inspection, and site supervision. I have assessed many existing structures during the projects, including, but not limited to, gathering documents, recognition of structural systems, rapid seismic evaluateion, determining the causes and extent of the vulnerability, checking damages, and cracks, and retrofitting (if necessary) based on technical and economic affairs. All these stages were performed in accordance with American codes and standards such as the Fema series, ASCE 41, and national codes.
Please see som projects in the portfolio, and files attached.
About the case:
You wrote that you have the model in hand, so it seems the structure is designed against gravitational and lateral loads. Now, it is sufficient to check the opening's local effects on the beams and floors.
Acoording to plan you sent you are considering cutting the main beam to arrange the lift. if so you need steel columns to transfer loads. otherwise with dislacement of lift to the south we have the better structural behaviour.
