Separate chapters deal with design, construction, and materials for formwork. Considerations peculiar to architectural concrete are also outlined in a separate chapter. Other sections are devoted to form-work for bridges, shells, mass concrete, and underground work.
Concrete Formwork Loads and Pressure Calculations. Following are the various types of loads and pressures act on concrete formwork: Vertical load. Lateral pressure of concrete. Horizontal loads. Special loads. 1. Vertical Loads on Concrete Formwork.
Lateral Pressure of Concrete • Recommended Design Values for Form Pressure • Gravity Loads on Formwork • Lateral Loads • Considerations for Multistory Construction
considers the updated lateral pressure provisions now provided by ACI 347. Expanded coverage is provided for wind loads, analysis of the shoring and reshoring process, evaluation of concrete and structure strength to withstand shoring loads, and design of shoring and bracing elements. This edition also reflects the latest changes in wood design
Throughout this guide, the terms design, design load, and design capacity are used to refer to design of the formwork. Where reference is made to design load for the permanent struc-ture, structural design load, structural dead load, or some similar term is used to refer to unfactored service loads on the structure.*.
Much of the PCA publication is comprised of tables of coefficients for calculating moment and shear in two-way slabs. These tables should simplify the calculations. We will refer to the PCA Rectangular Concrete Tanks design manual as PCA-R, and the circular tank design manual as PCA-C.
for Storage Tanks and Their Supports” in 1984, and amended it in the 1990, 1996 and 2010 publications. This current revised recommendation provides bulk material pressures for silos and further guidance on seismic design methods for storage tanks based on the horizontal load-carrying capacity in the structure.
