NEC - SE - CG code (Minimum loads):
The NECSE-CG provides a general framework for structural designer. Loads to be considered in the calculation and design of all types of structures are:
• permanent loads (minimum dead loads in particular).
• variable loads (live loads, wind and hail).
They will be complemented by accidental loads are seismic loads (in new construction and rehabilitation), subject to the NEC-SE-DS and NEC-SE-RE standards. Shall not be taken into account:
• temporary loads due to the construction process,
• dynamic wind loads,
• loads or accelerations due to moving vehicles, explosion, sinking foundations and others due to natural phenomena.
NEC - SE - MP code (Masonry):
This chapter presents criteria and minimum requirements for the design and construction of structures of unreinforced masonry, reinforced masonry and confined masonry, up to 4 floors. The requirements of this chapter are aimed at achieving an appropriate behavior of structural masonry buildings in low load conditions defined in the NEC-GCSE. Structures able to withstand all expected internal stresses (compression, tension, bending, torsion, etc. and combinations thereof), to deform and move permissible way to design.
Units: units will be used S.I. according to ISO 1000 Standard.
NEC - SE - HM code (Structural concrete):
The structural elements of reinforced concrete must comply with the latest specifications of the ACI-318 code. The seismic design will be in accordance with the NEC-SE-DS standard, indicating except Chapter 21 of ACI-318 code (Earthquake Resistant Structures). The provisions of this chapter apply to the design of buildings where seismic loads resistant system consists of:
• special frames,
• reinforced concrete structural walls.
This NEC-SE-HM is for reinforced concrete. For other types of concrete, not specified in this standard, it should refer to the following chapters of the ACI 318:
• Chapter 16 (Precast concrete)
• Chapter 18 (Prestressed Concrete)
• Chapter 22 (Single structural concrete)
International system of units (SI) according to the ISO 1000 standard are used.
NEC - SE - AC code (Structural steel):
These provisions consider that steel structures will be designed, manufactured and assembled using hot rolled profiles or armed assembled by means of welded plates.
These provisions shall apply where the reduction coefficient of seismic response R, specified in the NEC-SE-DS of these standards is greater than 3. The structural steel systems designed to higher-R 3 is expected to dissipate energy from movements design ground through inelastic deformations of the structure. For those cases where the rate of reduction of seismic response, R, is equal to or less than 3, no need to meet the requirements in these provisions, except for special systems of columns projecting where it must meet the requirements included in these systems.
The provisions in this chapter are based on the provisions presented in the ANSI / AISC 341-05 documents, ANSI / AISC 341-10 (Seismic Provisions for Structural Steel Buildings), 358-05 (prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications) and FEMA 350 Recommended Seismic Design Criteria for New Steel Moment Frame Buildings). These documents reflect the most current relative to the seismic performance of structural steel buildings in the United States knowledge.
Specifications and codes referenced in these provisions shall be those listed in Section A2 of the ANSI / AISC 360-10.

This code contains the requirements for fabricating and erecting welded steel structures. When this code is stipulated in contract documents, conformance with all provisions of the code shall be required, except for those provisions that the Engineer (see 1.4.1) or contract documents specifically modifies or exempts.
The code was specifically developed for welded steel structures that utilize carbon or low alloy steels that are 1/8 in [3 mm] or thicker with a minimum specified yield strength of 100 ksi [690 MPa] or less. The code may be suitable to govern structural fabrications outside the scope of the intended purpose. However, the Engineer should evaluate such suitability, and based upon such evaluations, incorporate into contract documents any necessary changes to code requirements to address the specific requirements of the application that is outside the scope of the code. The Structural Welding Committee encourages the Engineer to consider the applicability of other AWS D1 codes for applications involving aluminum (AWS D1.2), sheet steel equal to or less than 3/16 in [5 mm] thick (AWS D1.3), reinforcing steel (AWS D1.4), and stainless steel (AWS D1.6), strengthening and repair of existing structures (AWS D1.7), seismic supplement (AWS D1.8), and titanium (AWS D1.9). The AASHTO/AWS D1.5 Bridge Welding Code was specifically developed for welding highway bridge components and is recommended for those applications.

Seismic Behaviour and Design of Irregular and Complex Civil Structures II
Author(s)/Editor(s): Zbigniew Zembaty, Mario De Stefano | Size: 14 MB | Format:PDF | Quality:Original preprint | Publisher: Springer International Publishing | Year: 2016 | pages: 362 | ISBN: 3319142453
Irregular engineering structures are subjected to complicated additional loads which are often beyond conventional design models developed for traditional, simplified plane models. This book covers detailed research and recent progress in seismic engineering dealing with seismic behaviour of irregular and set-back engineering structures. Experimental results as well as special topics of modern design are discussed in detail. In addition, recent progress in seismology, wave propagation and seismic engineering, which provides novel, modern modelling of complex seismic loads, is reported. Particular emphasis is placed on the newly developed rotational, seismic ground-motion effects.

This book provides a gentle introduction to equilibrium statistical mechanics. The particular aim is to fill the needs of readers who wish to learn the subject without a solid background in classical and quantum mechanics. The approach is unique in that classical mechanical formulation takes center stage. The book will be of particular interest to advanced undergraduate and graduate students in engineering departments.

The book aims to provide an overview of the state of the art on the mechanics of arches and masonry structures. It is addressed to an international audience, arising from the international context in which the Associazione Edoardo Benvenuto has carried out its activities in recent years, under the honorary presidency of Jacques Heyman. The book belongs to the collection Between Mechanics and Architecture, born in 1995 from the collaboration of several renowned scholars, including Edoardo Benvenuto (P. Radelet-de Grave, E. Benvenuto (eds.), Entre Mécanique et Architecture / Between Mechanics and Architecture, Birkhäuser, Basel 1995).

Engineering Computation of Structures: The Finite Element Method
Author(s)/Editor(s): Maria Augusta Neto | Size: 12 MB | Format:PDF | Quality:Original preprint | Publisher: Springer International Publishing | Year: 2015 | pages: 314 | ISBN: 9783319177090, 9783319177106
This book presents theories and the main useful techniques of the Finite Element Method (FEM), with an introduction to FEM and many case studies of its use in engineering practice. It supports engineers and students to solve primarily linear problems in mechanical engineering, with a main focus on static and dynamic structural problems.
Readers of this text are encouraged to discover the proper relationship between theory and practice, within the finite element method: Practice without theory is blind, but theory without practice is sterile.
Beginning with elasticity basic concepts and the classical theories of stressed materials, the work goes on to apply the relationship between forces, displacements, stresses and strains on the process of modeling, simulating and designing engineered technical systems. Chapters discuss the finite element equations for static, eigenvalue analysis, as well as transient analyses.
Students and practitioners using commercial FEM software will find this book very helpful. It uses straightforward examples to demonstrate a complete and detailed finite element procedure, emphasizing the differences between exact and numerical procedures.
