6.4.2 Concrete Model Specifications for Tensile Strength

The units of the input data for the concrete model specifications for tensile strength (day, MPa, mm, °C) refer to the codes and are independent of the units in other input data or commands. If a time unit other than SI (seconds) is used for other input data or commands, then you must specify the time unit that you used in table 'UNITS' [Vol. Analysis Procedures]. For further explanations on development of tensile strength with time see Chapter 20.

CEB-FIP Model Code 1990 (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'MATERI'} \\ [-1.0ex] \rule{14... ...texttt{CEMTYP}\>\texttt{\textit{cemtyp}}$_{w}\,${]} \end{tabbing} \end{figure}$

FTMODL: MC1990 indicates the European CEB-FIP Model Code 1990 [16].
FCM28: mcomp28 is the mean compressive strength f_cm28 (in MPa) of a concrete cube or cylinder at the age of twenty-eight days.
CEMTYP: cemtyp specifies the cement type: SL for slowly hardening cements, NR for normal and rapidly hardening cements or RS for rapidly hardening high strength cements. [CEMTYP NR]

ACI 209 (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'MATERI'} \\ [-1.0ex] \rule{14... ...texttt{CURTYP}\>\texttt{\textit{curtyp}}$_{w}\,${]} \end{tabbing} \end{figure}$

FTMODL: ACI209 indicates the American Concrete Institute Model Code 209 [1].
FCM28: mcomp28 is the mean compressive strength f_cm28 (in MPa) of a concrete cube or cylinder at the age of twenty-eight days.
CEMTYP: cemtyp specifies the cement type: I for class-I cement, III for class-III cement. [CEMTYP I]
DENSIT: rho is the unit weight of concrete in kg/m³ . [DENSIT 2400]
CURTYP: curtyp specifies a curing method according to the ACI 209 code [1]: MOIST for moistening (the default) [MOIST] or STEAM for curing with steam.

JSCE (syntax)

FTMODL: JSCE indicates the Japanese Society of Civil Engineers Model Code for concrete [54].
FCK28: cstren28 is the characteristic strength f_ck28 (in MPa) of a concrete cube at the age of twenty-eight days.
FCK91: cstren91 is the characteristic strength f_ck91 (in MPa) of a concrete cube at the age of ninety-one days.
CEMTYP: cemtyp specifies the cement type: SL for slowly hardening cements, NR for normal and rapidly hardening cements or RS for rapidly hardening high strength cements. [CEMTYP NR]

JCI (syntax)
