When structures are subjected to blast loads, a significant level of structural damage is generated. Because it is difficult to prevent damage, an alternative method suggests using sacrificial layers (e.g., Aluminum Foams – AF), which will experience the damage and absorb energy, and not the structural elements. Several studies modeled the coupled response of sacrificial…

Ola presented her first PhD seminar on “Advanced Modeling of Aluminum Foam Preforming as Sacrificial Layers for Protected Structures.”

PI: Dr. Hezi Y. Grisaro CO-PIs: Prof. Aaron Sprecher and Prof. Arnon Bentur We aim to investigate the potential to implement the design of 3D-printed concrete elements in existing design codes and procedures. As 3D-printed concrete elements are getting more popular and offer advantages to fabricating intricate geometries and optimizing structural elements, implementing the reinforcement for structural components…

We tested several mix types and measured their compressive and tensile strength. We got up to ~160 MPa in compression and ~18 MPa in tension in this batch. Thanks also to Dr. Jaswanth Gangolu for the technical help.

We got two research grants to study the global behavior of structural elements under close-in detonations based on fast-running tools and relatively simple but accurate methods. Current design standards (e.g. CSA S850-12, ASCE/SEI 59-11, UFC 3-340-02, and others) suggest using nonlinear equivalent SDOF systems to study the global response of structural elements to blast loads.…
