Deformational analysis of prestressed high‐strength concrete members using flexural constitutive model

Journal of Civil Engineering and Management, 2005
In this paper, an attempt has been made to extend application of the recently proposed Flexural constitutive model to short‐ and long‐term deformational analysis of flexural partially prestressed concrete members. The effect of tension stiffening and

Flexural modeling of the Manila Trench based on subduction dip: comparison of north-south subduction differences

Frontiers in Marine Science
The Manila Trench, representing relatively young (16–36 Ma) subducting slabs, has been flexurally modeled to assess its subduction morphology. This modeling enables predictions of subduction-related earthquake locations and provides critical insights ...
