Beams or bending elements are normally subjected to bending moments in relation to their horizontal axis, which determines the upper and lower reinforcement of the section. If the beam is connected horizontally through a slab, reinforcement, prefabricated elements, etc., the horizontal effect of the loads does...
To achieve the objective of this work, the legalization of a covered terrace will be used as an example, in which it was detected that one of the beams did not have the necessary resistance to support the actual loads on it. Fig. 1 shows the...
During the process of extending a home, a contractor will demolish a load-bearing wall. The reinforcing beam does not have sufficient reinforcement to withstand the new loads, so it is necessary to reinforce the beam in a way that allows it to withstand these loads. There...
1. Introduction On certain occasions, changes to the structure arise, causing an increase in the actual loads. Due to this, some elements are subjected to loads that may exceed that of their original design, making it necessary to increase their capacity through the use of additional...
DESIGN GUIDES Introduction ACI 318 modified the criteria for determining skin reinforcement in large beams. Currently, tables are still used with a distribution that does not correspond to what is established in current standards. In this work, it is intended to obtain, in accordance with ACI 318 -...
Approximate calculation for the Reinforcement of a Section subjected to simple Bending Stress Introduction On some occasions it is necessary to calculate the reinforcement in the section of a concrete beam subjected to bending stress in an approximated form, either to verify calculations obtained in programs, to...
Minimum Amount in Concrete Columns When I began to study the design of concrete, it was established by the ACI-318 design standard, and the Cuban design standard, that the minimum reinforcement ratio in columns was 1%. I participated in the elaboration of the Cuban HA design...
Behavior of a Concrete Section Behavior of a Concrete Section Under Bending and Flexo-Compression Loads at Ultimate Strength Fig. 1 graphically shows the process that we will be developing in this paper. This is to determine the resistance capacity of any type of concrete section with reinforcement,...
Champlain Towers Collapse Structural Analysis Revisal After the article about the collapse of Champlain Towers South structural analysis was released, the criteria of the collapse continued to be under analysis. We have received more photographic information, and more up to date plans than what we were...
