Hinge/Pin - A hinge permits rotation without allowing translation (sideways movement), providing flexibility at that point. Roller - A roller support enables movement horizontally,…

This is an example of how to compute and distribute loads to beams from one-way or two-way slabs. In Figure 1-1, if the ratio of the short spans to the long span is greater than \(…

Since concrete has no definite modulus of elasticity. The value is dependent on the characteristics of the cement and aggregates used, the age of the concrete and its strengths. Ac…

Definition: Bending Moment can be defined as the product of a force \((F)\) and a moment arm \((d)\). The moment arm is the perpendicular distance from the axis \((y)\) at the mome…

Problem: Mr. Aw Adi recruited 10 people for the job. For 5 days the 10 people worked, but at the beginning of the sixth day, 3 persons left. How long will it take to finish the job…

Maximum View: Where should you stay so that you will have a maximum view\(\tan \theta = \dfrac{x_1}{x}\) \(\tan {\beta} = \dfrac{L}{x} \; \beta = \theta_2 + \theta_1 \; L = x_1 + x…

Varignon’s Theorem states that the moment of a force is equivalent to the sum of the moments of its components. This can be demonstrated using the figure . Let \(F_1\) and \(…

Definition:The Resultant force is the sum of all forces acting on an object. We often used sign conventions to denote Downard (-) and Upward forces (+).Resultant of a Rectangular L…

Cement is a binding material used in construction that hardens and sets when mixed with water. It acts as an adhesive in concrete and mortar, binding aggregates (sand, gravel, or c…

Assumptions in Strength Design Method for Flexure These assumptions were organized based from Fanella (2011). These assumptions will be a guide in deriving the formulas that will b…

Determinacy relates to the analysis of how fully a structure's internal forces and reactions can be determined using equations of equilibrium. A structure is considered determinate…
