Study Notes
Introducción a Estructuras
- Primera clase: Introducción.
- Fecha: Miércoles 02/04/2025.
Análisis de Estructuras
- Pasos para analizar estructuras:
- Definir la geometría de la estructura.
- Definir los apoyos de la estructura.
- Definir las cargas que actúan sobre la estructura.
- Definir el material de la estructura.
- Definir las secciones transversales de los elementos de la estructura.
Acción, Carga, Fuerza, Solicitación
- Acción: Causa externa que genera un efecto en una estructura.
- Carga: Manifestación física y cuantificable de una acción; puede ser puntual o distribuida (N/m^2).
- Fuerza: Vector que representa una interacción física; caracterizada por magnitud, dirección y sentido (N).
- Peso: Fuerza específica causada por la gravedad; siempre vertical hacia abajo (N).
- Solicitación: Efecto interno generado en la estructura; ejemplos: momento cortante, axial, torsión (N.m).
- Tipos de acciones: estática, dinámica, cualitativa, permanente, transitoria.
Conceptos y Fórmulas
- Inercia: I = (b x h^3) / 12.
- Elasticidad: E = 2'100.000 Kgf/cm².
- Área de un rectángulo: Largo x ancho.
- Fuerza: F = m x a (masa por aceleración).
- Peso: P = m x g (masa por la aceleración de la gravedad).
- Aceleración constante de la gravedad: 9,81 m/s².
Unidades de Carga y Densidad
- Ejemplo de densidad: 1000 kg/m³.
- Ejemplo de carga distribuida: 200 kg/m².
- Ejemplo de carga lineal: 3 T/m.
- Relación peso-masa: 100 kg equivale a 1.6 m x 10^2, equivalente a 9.81 m/s^2*100kg= 16,6 kg.
Solicitaciones (Efectos Internos)
- Solicitaaanes = Efectos Internos
- Tracción
- Flexión
- Compresión
- Torsión
- Cortante
Unidades
- Accion:
- Carga: N, N/m
- Fuerza: Modulo
- Peso: kg, kg
- lb
- N
Aclaración sobre Carga y Fuerza
- Toda fuerza es una carga, pero no en reversa.
