Structural engineering

Welcome to XC

Pursuing structural engineering solutions for society.

We strive to contribute to society with structures that fit with the 3 E's of structural art: Efficiency, Economy, and Elegance. Our senses are open to Nature, both for learning from its beautiful forms as for raising personal awareness about sustainability. In terms of technology, we develop, with self-imposed mandate for openness and knowledge-sharing, much of the software that we use; conceiving tools to enhance, rather to compete with, the creative human process of design.

XC tutorial 3: Properties of a reinforced concrete section obtained from a fiber-section model.

This tutorial deals with a simple RC rectangular section subjected to uniaxial bending. Two layers of reinforcing bars are placed at the top and bottom faces. By integration over the fibers, we obtain geometrical and mechanical properties of the section as well as its deformation under load.

Second tutorial: Vibrating string under tension

This XC-tutorial deals with a flexible string fixed at the ends and stretched to an initial strain. The aim is to determine the first three natural frequencies of lateral vibration of the stretched string.

First tutorial: Getting started with XC

This tutorial deals with a steel bar of uniform cross section whose ends are fixed from translational motion. The goal is to find the axial force in the bar subjected to a uniform temperature increase.

Tangled up with fibers

These days we are playing with XC fiber-material models of reinforced concrete sections. By integrating different fiber properties, we can find useful quantities relative to the geometry and tensional state of the section.

Analysis of instantaneous losses in prestress with XC

We have posted on the blog an article about the analysis of prestressed structures with XC, specifically, the article deals with the tracing of cables and the calculation of immediate losses in prestress.

Prestressed concrete slabs in XC

We are implementing in XC some developments to model prestressed concrete slabs.To test these tools, we create a 3D model of bridge with longitudinal and transverse prestressing tendons.

Analysis of a building with XC.

We have posted on the blog a case study that deals with a six-storey building with two underground parking levels. The displacements and internal forces are calculated with XC for several load combinations.
