v1.5. This Computer program (including software design, programming structure, graphics, manual, and on-line help) was created and published by STRUCTUREPOINT, formerly the Engineering Software Group of the Portland Cement Association (PCA) for the engineering analysis, design and investigation of buildings, bridges and structures.

1.2 spFrame Features. spFrame offers flexibility through its impressive array of features which include • Practically unlimited number of joints and members. • Second or (P-Δ) effects and tension-only members. • Proper shear wall modeling. • Hinged or partially-fixed element ends. • Shear deformations. • Translational and rotational elastic supports.

Three-dimensional space frame members have six degrees of freedom per joint displacements in the global X, Y, and Z directions, and rotations about the global X, Y, and Z axes. Space frame members can be subjected to forces and moments in any direction.

The element stiffness matrix is a square matrix proportional to the member degrees of freedom (e.g. a plane truss element stiffness matrix is 4 x 4, whereas a space frame element stiffness matrix is 12 x 12).

frame systems. Multi-purpose structur al modeling and analysis software for three-dimensional buildings and structures with robust, quick yet simple interface. spFrame calculates inter nal forces, reactions, rotations, and displacements using linear structural analysis. 54

Reinforced concrete structural software includes programs for column design (pcaColumn), beam design (pcaBeam), slab design (pcaSlab), wall design (pcaWall), mat design (pcaMats), foundation design, tank design, slab-on-grade design and frame analysis (pcaFrame).

The Equivalent Frame Method (EFM) presented in ACI 318-14 is illustrated in detail in this example to analyze and design two-way flat slab with drop panels system. The EFM solution is also used for a detailed comparison with the analysis and design results of the engineering software program spSlab.
