scikit-fem is a pure Python 3.10+ library for performing finite element assembly. Its main purpose is the transformation of bilinear forms into sparse matrices and linear forms into vectors. The ...

Rebar corrosion caused by chloride ion ingression is a critical factor leading to performance deterioration of in-service reinforced concrete (RC) structures exposed to aggressive environments. This ...

Concrete creep weakens the spring stiffness of stud shear connectors (SSCs) and increases the long-term deflection of long-span composite beams. The time-dependent properties of SSC are of great ...

Shear design of reinforced concrete (RC) beam involves the determination of spacing between stirrups. Shear is a word used for forces that work perpendicular to the longitudinal axis of RC beam.

The transfer of loads from a slab to beams is controlled by the slab's geometrical dimension and the direction of reinforcements. The load of the slab, including self-weight, live load, and imposed ...

Abstract: This letter presents new designs of time-modulated antenna arrays for circularly polarized shaped beams. Disk patches are used at the X-band as the elements distributed in nonuniform ...
