Formerly pcaSlab and ADOSS, spSlab is a computer software program for the analysis and design of reinforced concrete beams and slab floor systems. Two-way slab systems are analyzed using the Equivalent Frame Method. Beams and frames of up to 22 spans can be analyzed and designed. In addition to the design option, spBeam and spSlab have the capability of investigating existing beams and slab systems. spSlab includes provisions for slab band systems as well as punching shear check and deflection calculations using cracked or gross sections. For beams, moment redistribution, as well as combined shear and torsion design, are available. In addition to the required area of reinforcing steel at the critical sections, spSlab provides a complete reinforcing bar schedule that includes the number of bars and bar sizes and lengths. spSlab checks the applicable provisions of the selected code.
Formerly pcaBeam, spBeam is a limited version of spSlab. It includes all elements that apply to beams and one-way slab systems. Two-way slab systems are available in spSlab only and topics related to two-way slab systems are denoted with
