Spanish term
Caso Pv+Ph/Pv+Sh/Sv+Ph/Sv+Sh.
Spanish to English
Tech/Engineering
Construction / Civil Engineering
Calculation of stress/strain of steel mesh installed on a building - façades and terraces.
In a calculation report (MEMORIA DE CÁLCULO Reacciones sobre la estructura soporte al instalar en un edificio unas mallas metálicas modelo Eiffel-40100). The above occurs in a table with the following column headings:
Fuerzas transmitidas por las mallas (kN/m)
Caso Pv+Ph/Pv+Sh/Sv+Ph/Sv+Sh. Combinación con hielo 1.2 D+Di
Flecha máxima en el panel vertical 0 mm
Flecha máxima en el panel horizontal -55 mm

Primary waves
Main article: P wave
Primary waves (P-waves) are compressional waves that are longitudinal in nature. P-waves are pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than the S-waves. In air, they take the form of sound waves, hence they travel at the speed of sound. Typical speeds are 330 m/s in air, 1450 m/s in water and about 5000 m/s in granite.
Secondary waves
Main article: S wave
Secondary waves (S-waves) are shear waves that are transverse in nature. Following an earthquake event, S-waves arrive at seismograph stations after the faster-moving P-waves and displace the ground perpendicular to the direction of propagation. Depending on the propagational direction, the wave can take on different surface characteristics; for example, in the case of horizontally polarized S waves, the ground moves alternately to one side and then the other. S-waves can travel only through solids, as fluids (liquids and gases) do not support shear stresses. S-waves are slower than P-waves, and speeds are typically around 60% of that of P-waves in any given material. Shear waves can not travel through any liquid medium, so the absence of S-waves in earth's outer core suggests a liquid state.

I apologise for providing an answer from Wikipedia but it's enough to get you started.
As I mentioned, I'm no expert on the subject, although I do have some experience translating and reviewing texts from the civil engineering field.

Reference:
In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave. For example, sound waves are P waves at a high enough frequency to hear with your ear. An example of an S wave is wiggling or shaking a rope which is tied down at one or both ends.

I'm no expert but I think it's worth researching horizontal and vertical (com)pressional waves and shear waves.

Note from asker:
Thanks for your considerable efforts and very reasonable hypothesis, Helen, but I found the answer elsewhere. The first two are paño vertical and paño horizontal, understanding "paño" as plane. |

Discussion
Son mallas que cuelgan de una viga superior y son inmovilizadas por pernos a lo largo de la pared.
El metro de malla que cuelga tiene unidades kN/m o sea el peso. Cuanto más larga sea la malla, más va a pesar.
Ver lista de productos "Codina" entre los cuales se encuentra Eiffel-40100. Al final se encuentra el tema de la fijación al techo y la pared de la malla.

- Pv usually stands for "Vertical Load" or "Vertical Pressure."
- Sh often refers to "Horizontal Shear" or simply "Horizontal Load."

A shear wave that is polarized so that its particle motion and direction of propagation are contained in a horizontal plane.
